I also recommend FCEUX to emulate NES. To find a ROM just look for it (Pacman ROM or something like this)

Gonna try it, thanks for the answer!

-Activating Music storage prior to the run is allowed.

Is this referred to Merlin and Bugs not talking to save time in "dialogues/cutscenes"? I don't get how I do activate this :/

Yeah, you'll better wait some mods answer about it. Still I guess it's not allowed.

I personally use BGB for gameboy games, but I guess both are good options.

j x3 is just the same as j x9. Just drop one of them, this is supposed to trigger the fast text glitch for the very last part of the game

For CTR on emulator the NTSC-U is so much better than PAL language glitched
