NES emulation: high hopes by aspekt #33

Hi,

I used to test NES emulation using a set of demos, which use sophisticated 6502 tricks. I spotted MMC3 emulation issues while running high hopes:

DMC channel is not working/not implemented?
Some animations are just black

I will leave it here for further investigation.

It seems like the demo improved quite a bit in more recent versions of retro-go.

It's also a PAL demo, so add (E) or (Europe) to the filename so that the emulator runs it in PAL mode. (retro-go doesn't honor flag 9 because in most ROMs it contains garbage, so the filename hack is the only way to start a PAL game)
