Here you have a new version of Puck2099’s Master System and Game Gear emulator for GP2x.

Changes:

Fixed problem with FM sound. It should work now with european ROMs that didn’t work before (Out Run, R-Type, California Games…). Thanks to Steve Cain (shiffy) and Bob Forgan for reporting it.
Added support to Tweak RAM Timmings. By default it’s disabled, if you want to enable it just delete file “notweak” (and do the opposite to disable it again).
Added support to alternate control to CLICK button so you can use buttons combinations in new F200 and modded F100. Thanks to Ryo for his prior hack.
Modified main volume to a 50% if it detects that it’s running in a F200.
Deleted battery level and LED if it detects that it’s running in a F200.
Other minor changes.
