Setup:
RH8, kernel 2.4.20
PSOne (PSX) pad on LPT1 EPP/ECP using gamecon.c
xmame (x11) version 0.65.1
nvidia 1.0.4191 XFree86
devfsd-1.3.25

All -

I've noticed that my framerate drops by half (to 30fps) when I enable my
PSOne (PSX) pad using the linux gamecon.c driver. It doesn't seem to
matter whether I use the SDL or x11 versions of xmame. I've tried
several different -jt settings (only 1 and 4 work). Screen scaling and
extra options (-sl, etc) don't seem to slow things down when the
joystick is disabled. My processor is sufficiently powered and I have a
generous amount of RAM available.

Are there polling issues, or does anyone have any suggestions for
minimizing the performance hit when using a parport gamecon PSX pad?
This doesn't occur under MAME32 (and other Win32 variants), so it
appears to be specific to the gamecon driver.

Any suggestions or questions are appreciated. I'm kind of stuck, and a
bit bummed I have to boot into Windows to enjoy MAME at the moment.

Thanks again!
