fMSX is a famous emulator of the MSX, MSX2, and MSX2+ 8bit home computers. It runs MSX/MSX2/MSX2+ software on many different platforms including Windows and Unix.

It has been first written by Marat Fayzullin, and later Vincent van Dam ported it on SDL.

GP2X-MSX is a port on GP2X of the version 2.7.0.40 of fMSX-SDL from Vincent van Dam that ZX-81 had previously ported to PSP.

This version fix game compatibility issue (all games that required painter.rom cartridge)

Changes:

– Speed improvements in CPU and sound emulation
– Add missing keys such as HOME, GRAPH, STOP
– Add option to increase emulated sound volume (different from gp2x volume)
– Auto-fire mode, press RTrigger+X to switch it on/off (useful for games such as 1942)
– RTrigger/LTrigger keys can be used in the keyboard settings menu to navigate between Normal, LTrigger and RTrigger compose mapping.
– Add several new hotkeys :
. settings such as fps, render mode, auto fire speed can now be directly modified inside the emulator (no need to enter in the settings menu)
. quick save / quick load current state (no need to enter in the main menu)
– Default Hotkeys can now be set in the keyboard mapping menu (useful to add hotkeys on existing/previous keyboard files)
