implement open bus #4

Open ITotalJustice opened 2 years ago

ITotalJustice commented 2 years ago

firstly i need to find a test rom / game (ideally test rom) that uses open bus behaviour

ITotalJustice commented 2 years ago

this seems to be needed for minish cap. specifically for the title screen as it uses div 0 a lot (0 / X). if i HLE it or use the official bios, the game works. if i use normmatt bios and don't hle div, the title screen is very broken
