Ok here's the new version.

Improvements:
New Emulator, Gnuboy, runs considerably faster, 3x mode quite usable.

In-game menu, press the menu key, allows for the next feature.

State saving and loading! If 6 slots isn't enough I can easily increase it.

Heres the .deb http://chaoticbob.nfshost.com/maemo/...13-1_armel.deb

I strongly recommend you uninstall PyBoy before you install this one, just to eliminate any potential conflicts.

Known issues:

It can occasionally stutter for a while after using the menu due to the dodgy way I pause(or don't) the emulation.

3x mode doesn't work in non-fullscreen, but it wouldn't really fit anyhow so consider it a feature.

The on-screen buttons won't show until you click once.

In regards to changing the keys, in this new version you should be able to edit /etc/gnuboy.rc, at the top there are some lines like

bind a +a
bind z +b

Change the left hand ones to the keys you want, it should work, although you won't be able to press on the screen anymore.
