Games that hang
Problem:
- Prehistorik Man hangs after the level intro screen (black screen)
- Harvest Moon hangs after the initial game cutscene (white screen)
- Super Mario Land hangs at the title screen
- Dr. Mario hangs as soon a Start is pressed in the game options screen
Hypothesis: These hangs probably have to do with interrupts not working properly. Not sure what else could possibly be causing them. I do know that after I implemented more PPU functionality to pass dmg-acid2 Super Mario Land stopped working. Fairly sure it was working here: 9f468c73
