Hi everybody,
well, i solved one problem. I can now change the keys for the pifba (i called it MAMEpiFBA in my es_system.cfg)
the config file, that have to changed is ~/RetroPie/emulators/pifba/fba2x.cfg
The ASCII codes of the keyboard u can find at /usr/include/SDL/SDL_keysym.h
here is a promt ob my fba2x.cfg
[Keyboard]
# Get codes from /usr/include/SDL/SDL_keysym.h
A_1=308
B_1=306
X_1=304
Y_1=32
L_1=122
R_1=120
START_1=49
SELECT_1=53
LEFT_1=276
RIGHT_1=275
UP_1=273
DOWN_1=274
QUIT=27
next step is to map the keys from my keybord to the NEOGEO emulator, i use the gngeo-pi-0.85 emulator in my es_system.cfg
but i can not find the “insert coin” key i have tested all keys on my keyboard. In my ./gngeo/gneorc file the insert coin button is mapped on “3” but it doesnt work
So please help me to find the right config file for gngeo-pi-0.85.
