I was playing Megaman 2 today under PocketNester, and I got annoyed at the screen refresh problems when loading/saving savestates, so I took the code updates from Emulamer's PocketSNES update (Not the OpenGL update by Tala.) and applied them to PocketNester.
So now, even without the enhanced GAPI driver, you can get a full 60 FPS with sound, and the refresh bug is gone.
You can download the updated executable from

The only limitation is that you're forced to play fullscreen for now.
Let me know how it works for you. NOTE: This is only useful for the x50v, all other devices will see no difference over the 0.7 version.
