Emulator used: Bizhawk 2.10
Skips to the final boss using the select bug, but as of now, slower than just going to an earlier story state, since it needs to wait 100k frames. Done in GBA player mode in hopes final run could be console verified.
Proof of concept of triggering the real final chapter ending, while in a completely different stage. In this case, stage 28, Go through the grand hall.
I managed to get a whole bunch of glitched items at once without crashing while attempting to improve the TAS. Posting here in case it might lead to something.
Current improvement to the current any% published TAS. Does not use reset and the route apparently works on console. It can be improved further by avoiding coins.
