This only does the beginning of level 2-1. I stopped working on it at the time because I accidently deleted my RAM Watch, and it made me go "meh". Unsure what I'll do with this, so I'm uploading it for anyone to take over if they want.
Some new improvements were found (1-1 and 3-4 mostly), most of the run has been edited to add these in. Not the same lag luck this time around, sadly... Total of 96 frames saved.
Roughly 40 frames faster at the moment, hard to tell because of different emulator. Failed WIP however...
