Stunt Air by Nuova Videotron 1983
driver todo: (SOME OF THIS WILL NEED PCB REFERENCES / MEASUREMENTS)
- correct colour PROM decoding (resistor values?)
- correct FG colour handling (currently use a hardcoded white)
- correct sound (discrete stuff is for filtering? or drums?)
- correct remaining GFX / sprite issues (flicker sometimes, might need better vblank timing?)
Hardware info (complete):
Main cpu Z80A
