| franticf appears to want this to wraparound (nw) if anybody knows the TMS32010 better it would help if they looked at the wheel input (should be a steering wheel + single button) because I can't see how it maps, the other input port isn't read. Maybe it generates an interrupt per tick or something? page flip implementation also still seems wrong for this game. |
