thanks for the clarification tepples. Just trying to sort out what the issue is exactly, or could be. It does not make any sense to me how the burai fix fixes mickey but not the game it was originally intended to.

Easy: fixes Nestopia and we'll get the answer.
Hacking the IRQ counter latch with +2 fixes the game. Other than that, I have no idea.

thanks zepper. Just so i understand:Zepper wrote:Easy: fixes Nestopia and we'll get the answer.

this was the block of code added to nestopia to fix burai (but ended up fixing mickey)
NST_FORCE_INLINE void Ppu::UpdateScrollAddressLine()
{
if (io.line)
{
int a12_mask = ~((scroll.address & 0x2000) >> 1);
io.line.Toggle( (scroll.address & a12_mask) & 0x3FFF, cpu.GetCycles() );
}
}
so are you saying if i add +2 to this this will fix burai, (at the moment labeled a hack i take it) If i add +2 wont this then break mickeys in effect and other games that might rely on this behavior? Sorry to sound like a noob, i just want to understand your statement completely, thats all.

This is not the right way to fix it. You will break other games.
