6 | N64 pad
7 | Sony PSX controller
8 | Sony PSX DDR controller
The exact type of the PSX controller type is autoprobed
, so you must have
your controller plugged in before initializing
.
The exact type of the PSX controller type is autoprobed
when used so
hot swapping should work (but is not recomended)
.
Should you want to use more than one of parallel ports at once, you can use
gamecon.map2 and gamecon.map3 as additional command line parameters for two
more parallel ports.
There are two options specific to PSX driver portion. gamecon.psx_delay sets
the command delay when talking to the controllers. The default of 25 should
work but you can try lowering it for better performace. If your pads don't
respond try raising it untill they work. Setting the type to 8 allows the
driver to be used with Dance Dance Revolution or similar games. Arrow keys are
registered as key presses instead of X and Y axes.
