Cabinet-Friendliness Tips

Reassigning Inputs

If you're using Gens/GS with Wah!Cade in an arcade cabinet, you will probably want to map player 1's C or Z button to the spacebar. Some Linux versions of Gens and Gens/GS, however, have problems mapping buttons to the spacebar. To work around this, open ~/.gens/gens.cfg and scroll down to the "Input" section for player 1, and set the hex key code for the desired input to "0x0020".

gens.cfg file for Gens/GS:

 [Input]
 P1.A=0x0130
 P1.B=0x007A
 P1.C=0x0078
 P1.Down=0x0112
 P1.Left=0x0114
 P1.Mode=0x0035
 P1.Right=0x0113
 P1.Start=0x0031
 P1.Type=0x01
 P1.Up=0x0111
 P1.X=0x0132
 P1.Y=0x0134
 P1.Z=0x0020  <-- Player 1's Z button is mapped to the spacebar here.

Disabling Messages

The number keys are used to select save states. If you have 1 and 2 mapped to your start buttons, you may want to disable the save state messages that appear when you press them. Under the Options menu, select General Options and uncheck "Enable" under Message. Alternatively, you can set Message=0 in the gens.cfg file.

Exit on ESC

When the --quickexit command line parameter is used (as shown above), the ESC key closes the emulator.
