This forum is actually ridiculous when the majority of threads ask the same questions about how to do an RNG manip, which emulators they're allowed to use and where to get ROMs/BIOS images. There's no reason this can't be summarised in a stickied FAQ, then the threads in question redirected there and summarily locked.

To be fair, the allowed emulators are described in the rules for each category, so there's no reason those threads should ever be made in the first place. It's not like it's unclear; "The only allowed emulator is the latest release of GambatteSpeedrun (Currently r614) with a GBC bios image. All other emulators are banned."
