driver by Angelo Salese, based on early work by Pierpaolo Prazzoli and David Haywood
TODO:
- We need to patch a rom to get the games to do more; there's also a "rom test error 6"
in service mode (that is the g2-m.6a rom in progolf and g2-m.a6 in progolfa); probably
not a bad dump (progolf and progolfa have different encryption);
- There's a "rom test error 6" in service mode; the problem is in banking (from 8000 to 87ff)
- Hazards doesn't have any effect, might be the same issue as above;
- There's no "rough" display on the sides on the screen, might be the same issue as above;
- Map displays are currently wrong, they are drawn with the framebuffer;
- Flip screen support;
