I had a similar issue very recently and found it whilst searching through the many threads regarding ridge racer. So, i thought i'd revive his issue for others to see.
I own an original stand up ridge racer cab which stopped working recently. I used vivanonno to judge the emulation of the game (not bad, but no comparison to the original) with a standard cp.
I suspect the board is fried in the RR machine as it no longer boots up, so i wish at some point to re-create it in my cab via emulation.
Ive had the steering wheel and pedals out and all use 10k pots. I know there are a few ways of connecting my controls to a pc (U-hid, A-pac interface) but im obviously going to use the vivanonno emulator to re-create the ridge racer series.
My issue now is that i cant figure out how to configure vivanonno to use my steering wheel and pedals?
Could i configure the steering controls with the A-pac/u-hid sofware first, and then have the prog run in the background when i start vivanonno to emulate the joystick control?
Anyway, sorry for my utter ignorance in not introducing myself, being my second post 'n all. I go a little scatty when video game obsession creeps in......
