I already asked this in an old thread, but it seems that went unnoticed. I'm curious about the legality of using something like the hyperkin retron sq with an official game cartridge. Does the hyperkin affect viability of the run in any way?

I'm also going to ask this in the metroid 2 speedrun forum. Unless someone here would also know about that. Cause I want to speedrun off my official Metroid 2 cartridge rather than on emulator.

I have a question, do you think we can add categories for %100 with secret message, and any% secret message? I'd like to submit runs that do this, and I'd also like to see top speedrunner perfect the strats for it.
