I suggest you keep a copy of the emulator that you use specifically for speedrunning. I think that's what most of us do as the emulator itself is fairly small.

I have a more up to date one that I use for playing online casually as it loads faster.

Can we remove this post then? I just got super excited for the notion of being able to do a Marvin% run. ;-;

Edit: I understand that there probably isn't enough demand for the extra categories. I just think it'd be good to clear our this obsolete information. I'm not actually upset at all. 8)
