Odd quirk in Virtua Racing

[chillywilly]

I ran across an odd quirk in VR the other day - I had gotten a mouse for my Saturn and went ahead and plugged it into the second controller port. Everything was fine until I tried playing VR - I couldn't do anything in the menu after pressing START other than move up or down in the menu... and even that was backwards! After unplugging the mouse, VR worked like normal again. Very odd problem...
