In fact i recommend retroarch for most emus, for ppsspp use standalone App, latest nightlies. The xd is quite fast, even retroarch playa most snes games with bsnes core, which is very demanding. Running legacyrom at 1,8 GHz also helps with some games. I run tekken 6 fullspeed for example, and mostbgames run fullspeed. Use performamce governor for some games, activate multithread, disable simulate block transfers and use some speed hacks for some games. Let me know if this improves the speed on your device. There's so much you can do like replacing the default launcher with mLauncher, disable the transition effect in 'Developper Options' (Go to Settings->About phone and tap several times on 'Kernel version' before Developper Options will appear in settings)Įven remove the cpu hungry background services like Google Play, Location. Then go to 'Entropy' and set both Read and Write to 4096. It should help, especially if you have a high class SD-card. Go to I/O Scheduler and set 'Read-Ahead' to 4096Kb. If you can change the clock, do it and set it to the maximum. Go to CPU and set the 'CPU Governor' to 'Performence'. If you use Kernel Aduitor and your tablet is rooted then great, follow my instructions ! If it is not rooted then i highly suggest you do so, because you will be able to use apps like Kernel Aduitor and change your CPU settings. Try to set it to Non-Buffered video and enable all the speedhacks. You may want to play around the settings and i'm not only talking about the resolution.

I had a tablet with the same specs and it's not a very powerful chip nowadays. Your device is a GamePad Digital GPD XD 16 GB right ?
