I just did a first run on Super Gameboy 1 for the SNES and I didn't honestly know if it was allowed or not. Can someone let me know if it is?

It is allowed :)

It is not allowed, as it has a much higher frame rate than an actual game boy.

the time needs to be converted. Other than that, you need to get word from one of the moderators if it's allowed for this game or not.
