I see the rules you have, and I get that. What are the rules on FPS. Do you have to play the game at the native GBA 60FPS, would any other FPS be considered cheating?

I believe the GBA player runs at a slightly different FPS, but apart from that anything with a faster FPS I would assume would be cheating.

Yeah bro, I'd assume that as well; I'd just like to have one of the mods give me a definitive answer.

What is the point of playing it at a different fps?

Basically, any sort of change from what the native hardware was running is considered a no-no. When original hardware can't be played (as in the case of GBA games), we have to make sure we're using settings that are as close as possible to it.
