Hi, lots of people have said conflicting points about this including some mods on this site, so I'm just hoping I can get a definitive answer here to these two questions.

1. can I use 2 frames of run ahead on retroarch with the current snes9x core to speedrun dram?
2. is it the same rule for all kaizo hacks? Thanks :)

As far as I know using run ahead on retroarch is fine for all kaizo hacks

Nice one, thanks superben!
