Accelerometer issues

When i try to play certain games the accelerometer is totally wonky and doesnt work right AT ALL. i was wondering if this is a hardware issue that can never be fixed, a firmware issue or a kernel issue... any ideas?

Yeah, same peroblem here

When I try to play a Polar Bit game like Wave Blazer or Asphalt HD, etc., the controls are completely out of control. Other games like NFS Shift, and the Gangster games from Gameloft, appear as if they will load, then half the screen has ghost like cars and people.
Is this something that will clear up with Gingerbread or will we likely have to wait for Honeycomb (which I have read has been written for the Motorola tab with almost identical hardware to our G pads) ?
Has anyone found any games besides Angry Birds that res up properly to a 10 inch screen ?
Thanks in advance.

I could actually be the game, or a firmware issue or both. Some games work fine, some do not probably as they coded for a smaller phone screen that's in portrait mode by default.
I wouldn't recommend this tablet for gaming, yet. Too many issues that may not be worked out until the app makers start developing for tablets. You could also call CS to complain, so that way they know it's an issue (I've done this a few times, myself).

Not sure I agree that the G is not good for gaming. Angry Birds, Mini Squadron, Steambirds, Quake series, PSX and the down the road releases of Dreamcast and N64 emus have no equal with Tegra 2.
If solely for Android games and especially Gameloft games, 100% agree.

I used to think the sensor was screwed up in the tablet. More I play with things the more I believe it is the way the games were coded. They were not made to work on a tablet in landscape mode. Some developers did a better job then others and may have thought ahead.
Raging Thunder is a good example. Raging Thunder 1 has to be driven with the tablet sideways. Raging Thunder 2 works fine. Seems to me something may have been learned about how things should be coded between game 1, and game 2.
If the G sensor was bad no game would ever work. Since there are games that do work I tend to lean towards the game being broken, and not the sensor in the tablet.

I can't wait til the N64 and dreamcast emus.

Labyrinth works perfect so I'm convinced its the games themselves

I wouldn't recommend it for gamers yet because some games don't work. But agree that, when they do work, they work very well. Angry Birds, for example, is a game I almost wish didn't work.
But since it's hit or miss, it's not something I would recommend to a gamer. I figure that this will work itself out as more Tegra 2 devices are released.

I just figured that some of the games i saw working on the galaxy tab in the vzw should be working on this tablet as well but there were some issues with them not working. anyway i hope can create a database of games that work well somwhere on the forums and sticky it

N64oid!

This is a great Nintendo 64 emulator now available on the market!
Here's the link:
https://market.android.com/details?id=com.androidemu.n64
For me, using an Xperia X10 and Advent Vega (Tegra 2) Banjo-Kazooie runs smoothly.
But Super Mario 64 runs too fast! I asked yongzh (the developer) to add a framelimiter, so hopefully it'll be implemented soon.
I'm amazed at this, especially after looking at how hard development of alternative N64 emulators has been.
E.g. http://forums.ngemu.com/misc-n64-discussion/139653-porting-mupen64plus-android.html

Nice! Says it's incompatible with my device (ZTE Blade) tough, no love for ARMv6?

have to try on my huawei u8800/ideos X5

that looks pretty impressive.
I wonder how it'll run on a Xoom...

I plays really good, I found mariokart to run a bit faster than it should and Killer Instinct was playing really well but the menu screen came out larger than it should. Lucky I remember what the options were.

Wow, Majora's Mask, on my SGS.. Oo And, it is too fast !! Desactivate frameskip helps, and it's more smooth, but sound keeps emulated too fast...
Updates will be great, results are really impressive !!
Screen is stretched, i know that Glide plugin on PC helps to do a true widescreen... Could be great to adapt it !

WOOHOOO!!!!!

I'll go try it out real quick, so far I've only used it on my HTC Droid Incredible and Droid X, works great on both of those.
Edit: It runs really smooth and looks pretty good, it seems like .n64 files run smoother than .z64 files anyone else noticed this?

Well legend of zelda oot run almost perfectly on my atrix except in the beginning cutscenes of the game the sound glitched a bit but the frame rate was still good. But when I tried to get the sword in the beginning the screen turned black but the scound is current still playing perfectly. I dont really care about the imperfections with this emulator I just can believe one finally got released for android and how well it works.
Edit:
Apparently when I went to get the sword in the beginning my screen went black but the sound still worked. Still the creators did an awesome job worth it.
Zelda oot:
I think it was a random glitch cause i am now at the duko tree and no lag so far.
Edit again:
it happened again. Something is causing the video to go out and turn the screen black otherwise perfect frame rate for zelda oot
Super Mario Kart:
The game menu it self plays perfectly but when im try to keep the accelorator(forward movement) going, steering the kart and fire an object on the touch screen it seems to freak out. It makes it when i press A it only accelerates for a bit then stops then I have to repress a to start again.
1080 SnowBoarding(Love this game):
I tried playing 1080 snowboarding it ran perfectly till i tried playing a level then it just froze.
Goldeneye:
I just finished playing the first level of goldeneye on agent. It ran almost perfectly. There were a few spots of lag but over all goldeneye is not ment for this controller set up. But again there were no major hicups with game. I was able to complete a the first mission.

Ive sent him an email (his email address is in the market)
EDIT: He´s answered my mail and said that it would be possible to make it compatible on ARMv6 devices but he doesn´t wanna do it because he has tested it on his htc legend and said that it was very choppy and he doesn´t wanna get bad ratings in the market because of ppl who expect the emu to run at fullspeed on devices with insufficent hardware. So I guess we´re out of luck.

anyone here also using their hd2 to play n64oid?
mines runs like 2-4 games perfectly but the rest the sound is horrible and it lags sometimes like starfox, mario kart, zelda oot & mm, etc... is it cause i have the first gen of snapdragon cpu??? i have to set the frameskip to 10 and autoframe skip to get good gameplay but only on a few.
never the less this is awesome i cant wait till after some more updates 1.1 is already out =D

What rom should i attach the game to? I have never heard of having to do this.

ha im not a moron i have disabled sound and i know sound makes many games laggy (was using daedalus psp for a long time and realize that the first time i got it) i just wanted to know cause newer up to date phones like the samsung vibrant, galaxy s, etc run it better with less hic up i just wanted to know if anyone else realized this and wanted someone to clarify it
p.s. i wasnt complaining i was just curious curiousity and complaining are completely different please dont just start accusing

Banjo-Kazooie has some graphical glitches though it has always been a problematic game to emulate if memory serves me right. Also FPS could be better in many places despite the intense frameskip going on (HTC Vision at 1.5 GHz)

Yep, Banjo Kazpoie has some issues with graphics in emulation. But its still fully playable on my Fascinate, almost near full speed.

Thanks a lot for asking him! Let's hope he'll manage to make the emulator more efficient. Seeing how well FPse runs it's a shame...

Anyone using the wii classic pro controller with this? I can't seem to find key mappings that make sense for Goldeneye... Any suggestions?

Those were the original controls:
You use the main analog stick to move Bond around, and you use the L button and the main analog stick combined to aim your weapon and lock the camera on a certain position. B is to reload, A to switch weapon, Left and Right C to Strafe, Up and Down C to look up or down, Z to use weapon, R is the same as L.
Click to expand...
Click to collapse
Maybe B to ZL, A to ZR, C buttons to a,b,x,y, Z to R?
Or C buttons to the right analog stick, a to b, b to y? (Maybe Z to a, if it doesn't work well on R?)

very choppy on Nexus One playing Zelda oot.anyone know a good set up to run smoother than the pre setup?

Have you tried any other games? N64oid is still very new and conkers bad fur day was the most advanced n64 game made. Generally it's last to be supported. I'll try it on my play to test this theory, as I'm curious.
Edit: Yep, I'm getting the same thing. You'll just have to wait till an updated version with better compatibility comes out.
As an update,
working:
mariokart 64
zelda ocarina of time
mario party 3
sf rush 2
mario 64 (duh)
Smash bros (although no one has faces)
wave race 64
Not working:
Conquers bad fur day
Hmmm, only one so far..lots more games to try though

My list:
Working:
Mario Kart
Mario 64
Smash Bros
WWF No Mercy (character select messed up a little)
Wave Race (slowish).
ISS 2000
F-Zero
Zelda OOT
Lylat Wars (slow)
Not Working:
Excitebike 64 (no load)
Star Wars Shadows of the Empire (no load)
Star Wars Episode 1 Racer (messed up graphics, unplayable).
Paper Mario (no load)
Pilotwings (messed up graphics, unplayable).
ps. Haven't played ANY of the above game complete yet so game breaking bugs might be present.

Yeah I tried goldeneye... No cigar

just keep an eye on threads like this, when a new version comes out im sure people will be talking about it

Cruisin' USA sort of works, it's very choppy even with the frame skip set to Max (10). Also some graphics are garbled.
Checking in on Smash Bros also, works great but no faces. Some slow down and audio loss occasionally.

As a general rule of thumb, a machine needs to be 3 times more powerful to be able to emulate properly.
The Xperia Play can emulate the N64 flawlessly. But it takes time and can be a little tricky to program.
Developers generally work for free in their spare time. If you want to donate to them to help them pay for their time and get the emulator working better, quicker, then feel free to donate to them.

Hard to tell. Theoretically yes imo. But would be so much work to get it optimised. Will never happen.

enerp8 said:

Emulating on a device only three times as powerfull requires a lot of optimised code that will take a long time (It took quite some time before snes was even decently running on pc's, and a lot more coding is done for pc then the xperia play).
Non-perfect (not all games working, some a bit choppy etc.) PS2 emulation on phones will probably come when ps1 and n64 emulators work nearly as flawless on any mobile phone of that time as snes runs now on nearly all (smart)phones.
Personally I think it will take 3-4 years (xperia play 3 probably).

Some more I tried today:
International Track & Field - DOESN'T WORK.
Mystical Ninja - TOO SLOW.
Paperboy - CRASHES.

Omg i want conkers bad fur day to work sooo bad! want to play some Cavemen vs Rapters!! hehe i find the emulator runs a little slow sometimes...especially for Zelda OOT...any suggestions? or is there a newer/faster emulator out yet?

Doom 64 no go =/ loads just fine but right when u start the game u start inside the ground so u cant move or anything

Shame that every game that works with N64oid plays very smooth on the DX2 and gTablet, but control like drunken sailors (some okay ok).
Most games play slow mo on the Play, but the few that are smooth like Mario Kart and Mario Brothers play sweet.
Ironic.

Wrong rule of thumb
Its not 3x the power of the original system.
Its 12x to emulate is perfectly.
Just go look at the Gamecube emulator thread

[Q] What N64 Emulator worked with zelda?

I was watching a youtube video of a guy playing on a N64 app but i couldnt make out the name of it. He was pretty far in Ocarina of Time. Any idea which one it is?

N64oid is the best by far. you can get it on the slide me market its about 4$

But sounds good it can play things smoothly (more or less)

I should have my TF monday.... Still hasn't shipped yet but im waiting patiently.

I got mine yesterday
Tried mario64 a quicky and it was smooooth....
I liked the controller interface on mupen64 more though, going to give that a try later and see if theres any performance hit.
offtopic: so far Im quite happy with the TF Its quite snappy and the screen hardly ever misses any keypresses.
But... is there no haptic feedback on this thing?

well mine was finally shipped, just gotta wait now. i got the dock/keyboard for it yesterday and im rather impressed with it so far. I dont see the issue people are having with the keys being raised up a little.
90% of all n64 emu's can emulate Mario 64 with ease. its the other games that dont. i was floored zelda and smash bros ran as well as it did. As for conkers bad fur day, this was the first emu it was even playable one.

I played OoT a bit yesterday on both mupen and 'oid, and yea, 'oid does indeed run it smoother (cleared deku tree, <3 the FF on the 30min cutscenes )
But I miss some graphical settings . Jet Force got a shadow bug causing the screen to flicker all the time, while mupen plays it just fine (it has other issues though^^).
Its obvious you need both emus to get the most out of N64 emulation at the moment.

Blazing Star - SNK PLAYMORE - OUT NOW!!!

Love this game, played it to death in the arcade when I was younger. Came out today. I have not played it yet so I cannot tell you if its Xperia PLAY optimized, but I am hoping that since the King of Fighters was optimized (sort of) this will be too.

We spotted this earlier great game. Have tested and everything works D-pad and Fire as well as all the menus. The onscreen controls also vanish when press a hardware button. Made by the same people who did R-Type port, Metal slug port and they always seam to remember the PLAY

ARE YOU SERIOUS?!
Blazing Star is one of my favorite games ever! And it's easily the most fun sh'emup I've ever played. You have no idea how long I prayed PSP would get this game (and never did!). Now it's here with achievements?! Getting this immediately!

Mame/Neo/Cps Emulators are great but where is the challange. I like and brought these official ports (metal slug too) for 2 reasons. 1) Bluetooth multiplayer 2) a limit on credits. Where is the challange if you can keep shoving fake credits in, it makes these games too easy because you have no real death. Its like cheating and there is no point in that when you are only cheating yourself out of a good game. With metal slug on Emulator i completed in a hour (fun over). On the official port not even half way in and been playing hours worth. At least with emulators like Snes and PSX you have limits as its built in to the game (Saves states are also bad but still mean you have to get past the place your stuck on dying). I am happy to recommend these ports over the emulated way

Original MVS cartridge are 'free play' at will anyway, but you are right about arcade, nothing can beat the 1coin challenge and bt coop option is the best.
My previous bought of metal slug for android was a disapointment, few option, gallery mode, slowness this one seems better optimized. I think save state is a bless to train yourself in the hardest level without crawling again the whole intro + much more freedom to simply save your progress.
My fingers thank autofire as well. I found vsFighters a bit more difficult compare to the arcade because of the controller, xplay paddle is tiny and snk special moves can be tricky.
