Maybe it would be useful to set up a discord for speedrunning this game. It doesn't have to be much, but it would be easier to talk about stuff
A "single day" would be quite nice! An individual day run for each of the settings (spiders, bugs, etc) could be fun.
the overclock bug can be fixed, but it'd require hacking the game. I myself play with 18overclock and the PD speedhack + boost speed hack freq.
if you want to speedrun PD, don't overclock ¯_(ツ)_/¯
60fps will break some action blocks, running at 30 will prevent it. not a problem with the emulator, but the framerate this will happen in PJ64 if you overclock it to run at 60
I have never had that issue. Are you using the version found on shootersforever? The one specifically for GEPD at 60fps with a great mouse injector?
