So I was wondering if its possible for someone to create or start developing an application that can emulator x86/64 code on an arm architecture?
What x86 code, exactly, do you mean? Do you mean running native x86 code directly or do you mean taking Java or .NET code and running it?
Ultimately, pretty much *anything* is possible to emulate. However, emulating it in a way that it can run in a reasonable amount of time is unlikely to happen. There are just so many things that are limited in the RT version of the .NET Framework.
ok, im not exactly best qualified for this but ill try and explain
in short, no, you could potentially make an emulator for a given program, but to make some be all end all x86 emulator to cover everything would be massively inefficient and probably not possible
you primary obstacle is that RT uses managed code, that means MS tells you want you can and cant do, it gives you the frame work if you like and you can build what you want within that frame work but step outside it and do your own thing isn't possible (yet)
once you got over that barrier, next up would be to port every single function and call sent to the CPU to an ARM equivalent, ARM is like a tadpole compared to Blue Whale of X86 so it wont do everything on chip meaning youd need to also convert it in software to something it can do
It would be like trying to blow a golf ball through a garden hose
however, small limited programs that don't rely on many hardware functions and with limited calls outside of its own program would potentially be possible to emulate assuming you can get native code to work anyway
Surface RT - Paperweight
Surface Pro - Glorified Tablet/Notebook
Just go with the Pro, it will make life much easier. The whole emulator debacle isn't even necessary if you just go with the logical choice.
I mean the Tegra 3 is awful as an SoC--I don't know what moron said Quad A9's are better than A15's, not to mention the GPU is junk compared to an SGX.
Overall Micro$oft shot themselves in the foot.

Actually Visual Studio 2012 could technically support building desktop applications to run on Surface RT and other RT (ARM) tablets. However, at this time, Microsoft is also allowing Microsoft signed applications. And, I heard that if you disabled that check in the registry, then you get blocked by RT. It is definitely possible that in the future, Microsoft might allow desktop applications to be recompiled for RT.
In the meantime, Remote Desktop is wonder in that I can connect to my Windows 8 laptop and use it to run any application with almost full touchscreen functionality. So, combining a Surface RT and a Windows 8 computer is ideal for me.

Add it stands, you can't even really disable UAC without breaking Metro in full Windows 8 (the UI setting to disable it doesn't really disable it). They have that thing locked down pretty well!
You can enable test-sign mode on RT, this would allow you to run your own ARM desktop apps, signed by your own cert, not with MS one. This is absolutely legal, but it can be closed by MS in some of the new hotfixes (and they'll definitely will, when this mode would be used to run cracked apps).
It is really possible to make a working x86 CPU emulator that would allow you to run x86 windows programs on RT. Just remember my port of "heroes of might and magic" 1 and 2 for Windows Mobile - it was more difficult to make it, as WM had a more limited Win32 API than Windows RT has.
I'll make a nearly universal emulator for RT when I'll buy a device, project is already started and has good results. But I'm waiting for a device that is based on quad-core Snapdragon S4. I would not recommend buying Tegra devices, 4-core Krait beats them in CPU and 3D speed. And high CPU speed would be necessary for smooth x86 emulation.
Quad A9's are better than A15. If you wasnt too busy kissing jobs ass, you would know this. Tegra line is alot better that any apple "cpu"

@Jaxidian: Disabling UAC disables Mandatory integrity Controls, which is how the sandboxes for both IE and Metro-style apps are implemented. Metro-style apps check, when they are launched, if they are running in such a sandbox, and exit if they aren't.
Disabling UAC is, and always was, a terrible, idiotic thing to do, and I truly don't know why MS made it an available behavior. Just set it to auto-elevate without UI instead, if you really can't stand having proper principle of least privilege in your OS. This is a little more complex (you have to use the Local Security Policy editor, which can be launched by typing "secpol.msc" into Run or by going into the Administrative Tools) but is a much better solution as things which explicitly want to be run with limited permissions (sandboxing) still can be.
@dazza9075: Dosbox is an x86 emulator that is already available on other ARM platforms. It just doesn't support the (many) x86 opcodes that have been added since the 386. It certainly can't do 64-bit. However, it's fine for running old DOS programs, including games. Somebody should port it to the Windows Store if possible, or at least see about making a homebrew build of it that we can run on RT devices. This is totally not my area of expertise or I'd do it myself.
A full x86 emulator, like Microsoft's old Virtual PC for Mac (except running on ARM instead of PPC), is technically possible. It's just hard. It sounds like some people are already working on this, though.
Regarding publishing DosBox, Bochs, Qemu, ScummVM and other emulators to Windows Store - they would be unable to pass the certification. Read the requirements here http://msdn.microsoft.com/en-us/library/windows/apps/hh694083.aspx
3.9 All app logic must originate from, and reside in, your app package

For emulators - app logic resides in an emulated program that is typically not present in app package.
By the way, Microsoft Internet Explorer can't pass this check too - as it downloads and executes flash from web. But MS is already known for its double-standards.
The other reason why those apps may be refused:
3.5 Your app must fully support touch input, and fully support keyboard and mouse input

Old programs (games at least) may be unusable without keyboard or mouse. My own program was refused for this reason, because it is unusable without hardware keyboard.
It is possible (and really easy) to port Bochs or DosBox for RT as a "desktop" application (making a "metro" port would be a bit more difficult). I can do that myself when I'll get hands on a Krait-based quad-core RT device, if someone would not port them earlier.
Regarding Tegra 3 vs Krait - Krait is not directly based on A9 nor on A15.

But its only a matter of time before we figure out a way to sideload metro apps without going through the store.
So after playing with my Surface for 5 days now, it is obvious there is a lot of capability in the back end through the Desktop. II have networked printers, and drives at both home and office going, streaming content etc. It is very capable for what it is, way beyond any other Ipad and Android tablet out there. So it seems to me it is just a matter of time before some XDAer figures out a way to unleash it and possibly load other programs (non-RT) programs some way. We know the official MS word is no, but it seems to me it is a fully capable Win8 machine that just has some goierners on it and limited processing power, just waiting to be cracked.
Am I just dreaming?
I would love to see this happen. The one thing holding me back from purchasing one. I'd love a Windows 8 Pro version tablet at the Surface RT pricing but wouldn't we all...
I dont think rt can run x86 app properly. Because the cpu is not as good as x86 core. I am interested in porting rt to compatiable device such as tergra 2 and 3 pad.

I don't think it's necessarily about the Tegra being "as good" as an x86 - the issue is that you'd need an emulator, or the source for the x86 app which you'd then need to re-compile for ARM. I believe MS made a developer toolkit available that allows simpler conversion from x86 to ARM but it's still up to the app vendors to do it.
In theory, the same code could compile for both x86/64 and ARM (RT), but VS2012 will not allow you to compile an ARM desktop app. There is no legit way to write/compile a desktop app on RT. Its an arbitrary BS limitation put in place by MS. You cannot side load apps, everything must come through the MS store, RT enterprise being an exception... which doesn't help us. And the MS store will only offer Metro apps. MS office shows that's desktop apps are fully possible, albeit recoded/recompiled for ARM, but MS will not allow it. In an ideal world, RT would be a fully supported OS, and the likes of Adobe and others could release desktop apps for RT, but sadly it won't happen.

Why do you say that?
Because its not allowed, only metro style apps published through the app store are allowed. Even if you compile compatible desktop software, the OS won't run it. Its a closed sandbox.
At best we can hope for a "homebrew" community to compile open source software, and find some hacks to get it running.

Hello,
I’m a happy owner of the Surface RT and I just wanted to add my 2c.
I think that Metro UI is great for tablet, but lacks apps !
So I cannot understand why Microsoft didn’t include .Net on this platform ! I think the main goal and the first “Homebrew” must be recompilation of Mono for ARM. As this will allow us develop a lot of programs, quickly and using “good” tools (Visual )
I just started to study WinRT and I’m already hitting a lot of blocks (For instance, I cannot find a way to open Shared Socket ! So if any other app listen on 1900 port, I lose my SSDP discovery... )
But I think recompilation of Mono is definitely a way to go ! I think i’ll try it this week-end, if I have some time, but It’s sure I will not be able install on my surface As for now it seems to be impossible to enter Testing Mode on it.

I think people seem to be missing something here (well, not just here, on other threads/forums.blogs too). MS have essentially (it’s really quite impressive) ported over the entire Windows OS to run on ARM – and this includes all of .NET v4 with supporting libraries/DLLs.
You only have to pop to C:\Windows\Microsoft.NET\Framework\v4.0.30319 on your Surface RT to see – all the same libraries for the same version of .NET a x86 desktop seem to be there - including Linq, SQL, reflection etc.
Now, this could be really great news! I’d bet that it would be entirely possible for standard .NET applications (by standard, I mean programs that only use managed code and nothing legacy) to be reasonably easily recompiled to run on ARM - ideally as easyily as changing a drop-down!
Furthermore, this is all supported in Visual Studio, it’s just locked down a bit - I’ve been able to compile, with VS2012 (and a minor tweak to remove the ARM compile block) a simple command line EXE for ARM (using .NET calls – though only in C++ which is a shame). The problem is, as soon I open it on Surface, I get an error saying the ‘digital certificate’ couldn't be validated – a common issue which has a simple fix documented online. The catch... that the instructions to remove this block don’t work with secure boot enabled, and - at present - we can’t disable this on the Surface (on normal PCs this can be turned off in the bios).
So – the key to all this, is for MS to open it up (not impossible, but who knows if or when) or for someone to get round this secure boot/certificate requirement. I’m sure there’s some smart people on here with abilities to work on, and hopefully succeed in doing this. Even if people aren't able to work a way round this block, I'm hopefully that eventually MS may release some firmware update tools that someone can hack to switch off UEFI secure boot. Or perhaps someone at MS or a partner may leak some file/app/boot that unlocks this for dev/enterprise purposes.
I look forward to it happening!

Everything doesn't have to come through the MS store, you can install applications that you build in Visual Studio 2012 for Windows Store, create an appx package and choose not to publish it in Windows Store. VS2012 then creates an appx package as well as a PowerShell script that you can run on Surface, accept security warning, get the developer's license on the device (it's free) and that's it!
It is fairly obvious why MS does not allow installation of "Desktop" apps on ARM tablets. Otherwise dev's would get lazy and just recompile desktop apps for ARM. The experience on a touch tablet would not be great on (unmodified) Desktop apps, hence Microsoft set this constraint on Windows RT in order to push dev's towards making a proper touch friendly app. The result is of course the lack of apps initially, but in the long run the benefits will be a greater experience as the apps would be optimized for touch.
Sure there are obvious downsides to this strategy, but the decision itself makes a lot of sense from a useability standpoint. You already read the complaints in reviews about "Office" not being Metro-style and unfriendly to touch. However this is naturally a decision due to time constraints, because MS would have also preferred to not include a desktop on RT. Office is the selling point now, to gravitate people towards RT and when there is enough demand, the touch friendly (Metro) apps will flow in eventually

Hmmm, sorry my bad, didn't look enougth to find .Net assemblies.
As for open it for MS, may be, maaaay be it's the same scheme which they followed with Windows Phone 7.
No native developpment for 7.0 -- 7.8
But they open it for 8.0
May be they just want to force people developp Metro app to populate the store first.
So where's the best place to get one?
I'm looking into buying one very very soon, I found some on ebay for $585 with the cover, That sounds like a win to me. I wish QVC had it, That'd be lovely.
I'm praying we get a work around for all this, But still If the device isn't made for it, I can't be mad that it doesn't do it, That's like being angry that my car doesn't fly.
But it's such a tease, it worries me that I'll have an entire desktop, Sitting, Obselete, With nothing but Office, which I wont even use.

It is made for it. It has the full desktop, and the full desktop Office suite. Its a big tease. The whole "do more" campaign advertises you can "click in" and have full laptop productivity with touchpad and mouse/keyboard. Except the only software to take advantage of it is desktop IE and Office.

Hi everyone.
Could anybody compile BlueStacks App Player for Windows RT?
It would be great to use this app on our tablet with Win RT
I use on my laptop (win7) and wish o use on my Surface RT
Official site
Thanx a lot
It would be a great app to have, but seeing that it's not open-source there is about zero chance of it ever getting ported by the community.
Your best bet is to just hope that they (the actual makers of the app) decide to bring it over to RT, which is possible but unlikely.
Search next time; the devs here are up to their ears in requests for closed-source applications and are pretty fed up with it. Sorry.
They've actually already stated that it's coming...
Not explicitly. They hinted at it in a Help forum post, but never confirmed or denied it. And that was months ago.

Actually they had listed on their site that they were working on an ARM version.but not sure if they still are. Seems unlikely MS would allow it in the store due to direct competition with the windows store.

MS doesn't have a whole lot of control of things outside the Store. They could side-load an app pretty easily.
The vast majority of RT devices aren't "jailbroken" for sideloading arbitrary ARM binaries. Also, remember that RT doesn't (currently) support OpenGL, which means any Android apps/games that use advanced graphics won't work unless BlueStacks write and include an openGL-via-DirectX compatibility layer.

I meant side-loading a Metro app, which can be done by just about everybody.
Cant sideload metro apps without a developers certificate
Derp. Yes, of course sideloading is the obvious way to go about it. Getting the dev license is easy, and yeah BS would have to sign their app, but that's not exactly difficult and their cert doesn't have to be signed by anybody else; it just requires that the end user install the cert before the app if it doesn't already chain to a trusted authority. The appx installer script automates all of that, though.
That said, the OpenGL issue is still there. Don't count on 3D games, at a minimum, working.
Don't forget however, that all of this is pretty much irrelevant right now. The Surface lacks the power to run Bluestacks. On my 6-core 2.3 ghz 6 gigs of ram computer with a great graphics unit, Bluestacks is still relatively slow. Just imagine it on the quad-core 1.4 with 2 gigs of ram that the Surface has. Not to mention it's on ARM, which is considerably less powerful than x86 or x64.

I dont think bluestacks is a multithreaded application in which case your 6 cores would be irrelevant and it would be purely down to your 2.3ghz clockspeed, which is not high at all. 6gb of RAM would also be irrelevant as no android app requires that much RAM so it simply wont be needed. GPU, not so sure what happens there, most of the apps I try running dont seem to enable my GPU at all so I am not sure if bluestacks is using software or hardware OpenGL, but then I havent tried any 3d games or anything. It runs ok on my 3.5ghz AMD athlon 2 but its not always as perfect as lets say a nexus 7 tablet running android natively.
I'm admittedly not 100% sure on how BlueStacks works (is it a native x86 DalvikVM, or is it emulating a full ARM system?), but it should be, at least in theory, possible to get it to run as naively as it does on Android by just porting the DalvikVM to Windows RT. That should result in speeds at least similar to a lower end Android tablet (Windows is bigger and has more cruft than the linux kernel that's running the DVM). With some sort of reverse WINE scenario it should also be possible to get a degree of binary compatibility for native libraries/addons.

Sort of, yes. But still, that means the Surface would be way less powerful. Also, my RAM is EATEN by Bluestacks because it's not apps that are the problem to run, it's Android. You're basically loading an entire virtual machine onto your RAM to run, in a program shell, then running Android apps on top of that. So the power of the device does matter... however:

Bluestacks would have to run a full emulation of ARM in order to run all apps, right? Because when you install native x86 Android, it runs very few apps from the store, because they aren't compiled for ARM.
Netham45 could be right though that we could kind of make Android run natively, though I'm highly dubious about it happening through Bluestacks. Bluestacks most likely won't make an ARM port (especially cause I doubt Microsoft would allow it in the store) and if we did have access to source code, it's still built around running on Intel processors, and would probably have to go through all sorts of unnatural emulation... So making a totally separate Android program from scratch (which would require inordinate amounts of work) would probably be the best bet.
No. I think bluestacks is actually "just" a port of the dalvik VM to run on windows.
Android apps are not compiled for a specific CPU type. They are compiled for the dalvik virtual machine which is in a way similar to the java virtual machine, in fact a dalvik applications source code is java source code hense why many people say android apps are java, in reality the dalvik VM is very different from the java VM and the 2 are not compatible.
The vast majority of apps do actually work on x86 just fine.
The main problem is that google restricts apps based on your device and often it doesn't recognise x86 devices so doesn't show results, the default app manifest files don't actually restrict platform but many devs set them to arm for some reason. With various tools to spoof what device you appear as you can still gain access to thses other apps.
The problem apps are those that use the NDK (a small minority). NDK apps do have native code, but not just for ARM. The NDK default settings are to generate binaries for ARMv7, but it can be set to x86, ARMv6, MIPS or to compile multiple binaries for a mixture of the above (causes its own issue as it includes the binaries for all platforms in one APK which loads the relevant binary at runtime, good for compatibility as one APK covers all devices but makes the final APK massive). x86 devices of course cannot run ARM compiled apps which does include a few big name apps.
I don't know if bluestacks has left it as pure dalvik VM on x86 or if it does include an ARM emulator for the NDK but it certainly isn't just running an ARM emulator and tyen android atop of it.
I don't experience the ram eating effects you mention either.

That's exactly what my understanding was as well, although what I'm about to say somewhat contradicts that.
Interestingly, http://www.bluestacks.com/technology.html says that BlueStacks is "fully configurable" and that it "supports" Windows on ARM as well as x86 Chrome, even though neither of those are actually available today. So, not sure if that page is before or ahead of its time.
"BlueStacks employs a lightweight, optimized, soft hypervisor with deep enhancements to support "embedded virtualization". End consumers can enjoy the full Android environment through BlueStacks, or just install Android app icons directly on the Windows desktop."
What the page basically says is that the core virtualization that BS uses is very easily configurable to different combinations or permutations of OSs; that the technology can just as easily run Windows on Android or Android on Chrome as it can Android on Windows, which is the only current release. It also implies that BS can do BOTH a mere dalvik vm (just install apps to the Desktop) as well as a complete system emulation (full Android experience).
There may be hope for RT yet.
As far as I remember, Bluestacks is using QEMU as there base platform. So it's probably still running ARM code in emulator.
I am looking at if we can port the Dalvik VM over to Windows RT. Anybody want to join the explorations?
So far I can see the Dalvik VM has lots of generated ARM assembly code and have huge dependencies on linux.
Porting would need quite a bit of effort.
Developers from Windroy has done it for the Windows X86 platform. If they can do it for Windows RT, it'll be much easier.
Right now 8.1 is a preview but what happens when it is fully released? Will windows RT auto update to it even if we don't like 8.1 and want to stay on Windows 8 RT?
I know you can disable auto-updates by hacking the registry but Id rather not have to do that.
Any way to keep automatic updates but ensure your system never upgrades to 8.1?
Why? 8.1 works great.

Windows RT is supported by WSUS. I never tested it myself, but you can setup your device to get updates not from MS site but from your local WSUS server - and just don't approve there the updates you don't like.
And similar to earlier service packs - there would be an "8.1 blocker" (look for Win7 SP1 blocker here: http://www.microsoft.com/en-us/download/details.aspx?id=22464). As this is just a registry key - it may work on RT too.

One massive issue with 8.1 which is enough to keep a large user base from updating: jailbreak.
Once there is a jailbreak for 8.1 though, then your argument would be valid.
Not sure why you wouldn't want to run updates but so far Windows 8.1 rocks! Makes RT so much better.

You talking about a jailbreak for 8.1 RT? Is so what type of stuff can you do with the jailbreak?

Not on the Asus Vivo RT it doesn't :silly:
8.1 really f#&@'s up the trackpad
Wow that's good to know.. I'm currently running it on a Dell T3500 desktop both Surface RT & Pro.
Are you sure it's not a driver issue. Maybe Asus have some updates available for track pad?
@Dane Reynolds: You new here? The Windows RT jailbreak has been a pretty big deal - especially on the RT Dev&Hacking sub-forum here - since its initial reveal over half a year ago. It removes the signing restrictions that Microsoft uses to lock out third-party desktop apps. With the jailbreak, you can:
1) Run .NET 4 (or later) desktop programs.
2) Run open-source Win32 desktop programs that were recompiled for RT (there's a list of them; check my sig).
3) Run a handful of programs specifically written for Windows RT tablets, including an x86 emulation layer.
4) Run various non-.NET legacy programs (some x86 through the emulation layer, some Java through IKVM, some Python through an incomplete port, Perl, Ruby, Lua, and a bunch of game engines).
5) Install third-party drivers (such as the open-source program Process Hacker uses).
Windows RT 8.1 breaks the method used to jailbreak RT 8.0. There are people working on getting it back - the OS is a hell of a lot more useful when you can run things like PuTTY and 7-Zip and even WebKit-based web browsers - but until them, most people that hang out around here are either dual-booting 8.0 and 8.1 (if they have enough space) or just sticking with 8.0.

Nah, I've been here since RT was released, I heard about the jailbreak but was never interested, but the only reason I wasn't interested was I never found any fun stuff to do with the jailbreak.

no fun stuff? Quakes 1, 2 and 3. Numerous other games, MAME I think.
Python.
.NET
FreeDownloadManager
a torrent client
An html5 browser other than IE (hopefully chromium or Firefox eventually)
PuTTY (would be an absolute must have for me)
Loads of other software many either useful or fun or both.
It really opens up the desktop side of RT
Damn, quake sounds fun and I could use chrome ... I kind of regret getting 8.1
I see the use for a jailbreak but I think it brings the OS backwards. These desktop apps aren't optimized for touch. I think building apps for the new interface is the way to go.
Funny; I get around fine using touch on the desktop (no, my fingers aren't even tiny). Well, except for typing. That sucks, Desktop or Metro. So, I have a Touch Cover, which makes typing a lot nicer. It also has a trackpad, so I only use touch when it's better than using a trackpad.
So, now I have a keyboard and pointing device, in addition to touch, for the device to be useful to me. Care to explain to me again why using apps which are amenable to all three input methods, instead of only one, "brings the OS backwards"? Because the way I see it, taking a multi-input device and excluding all those apps which aren't (over) optimized for a single form of input is a hell of a lot *more* backward...

I love quake and doom, been playing through doom again on my PSP actually (CFW-PRO to effectively jailbreak the PSP, then there are 2 or 3 ports for PSP)
Chrome isnt out for RT yet. GoodDayToDie had a look, but its complicated. Kudos to him for taking a look anyway, but so far 1 guy on his own hasnt managed to do it. Firefox also has its own issues. We may or may not see them eventually though. The jailbreak would be the first step before you could run them though.
As for 8.1. Trig0r has 8.0 recoveries for the surface RT which you could use to downgrade. Hopefully someone will get 8.1 jailbroken soon too, but microsoft patched the exploit that was being used before.
Thanks, I might ask for a recovery as I love gaming, speaking of gaming i know the Surface's hardware isn't high enough to run games but i was wondering if Onlive would be releasing an app for RT.
That would actually be a legitimate use for OnLive... wasn't sure I'd ever see one of those.
Surface (Pro or RT) are fine for light gaming, or for running older games. The RT does actually have NVidia graphics, they're just really underpowered. The Pro has only Intel graphics, but the Intel GMA for the i5 might actually be more powerful than the RT's Tegra 3 (haven't checked). In any case, there are lots of games known to work (if not always at max resolution / quality) on the Pro, and the RT has a number of older games which have been ported over working fine, and some old x86 games that run in the dynamic recompilation engine also working (though so far as I know, none of those ones are 3D).

I own VivoTab RT 3g - no problems with trackpad in 8.1. Currently I have no major problems with 8.1 except for the blinking screen issue that is present in 8.0 too. Even VPN works fine, so I finally can connect to my workplace and read email with Outlook, use RDP or Citrix Receiver.
recently i'm writing a win desktop app that requires a more modern ui (i.e. metro ui in a desktop app). my first thought is to go wpf, but that option died when it occurs that the app needs to run on surface rt tablets too (jailbroken). so a torturous route would be to write my own custom controls and put them on winform, but i suspect there can be a easier way out. would Qt be possible? any other wpf-like choices? tks!

For my RT Desktop Store, I have used the MetroFramework (link below), it's a WinForms implementation of the ModernUI for Desktop apps. Easy to use and may be just the thing you are looking for.

Did you mod anything to make it work on rt? Tks!

Winforms .net code -should- run verbatim on the RT, as long as it's targeting .net 4.5.
