can you try Blast Corps, i am unable to finish some levels because of broken controls, same rom finished the game on my PC+Project64, i am suspecting there are still some Control emulation bug
its the 2 levels that come after the Flying Robot Tutorial with 2 Jet engines (lvl 3 and 4)
The RDU car should have
Press A (B on switch): Move Forward
Press B (Y on Switch): Move Backwards
Press R: Turbo Boost (right now it boosts from front of car........)
Left Joystick should let you steer car to any direction, but it doesn't work at all.
please check
Common Guys at least one person other then me is a Blast Corps Fan
