So, recently I uploaded a time of 3:59, however, this time was only possible due to my emulator being exceptionally fast and essentially removing all the loading times (the "One Moment Please") screens. As such, I talked to a few individuals (CerealKiller and SnurgleStreams) and have decided to try and create a load remover here: https://github.com/Ksodlehe/MathRescue_LoadRemover
The idea is that the load remover makes all runs equal, as slower emulators will not be punished.
It should be noted that this load remover has only been tested with "DosBox SVN-Daum" and not the original DosBox emulator.
As the person who did a ton of the updated and initial routing for a ton of the categories, this makes me want to get back into running medium/hard/All collectables again plus finally taking the time to learn episode 3. the only other thing I think that is gonna make times faster at this point is to remove the bonus stage unless the load remover does that.
