I have loved this game and ran it for a long time, and am thinking this will be my next TAS. The category I am thinking of doing All Levels. The game is divided up into 2 sets of 15 levels (with 1 lategame level being identical w/ a different name, and the bosses being the same). I am unsure how to handle switching between sets of levels, as they both activate credits, so I may just reset after dealing the last hit to the final boss in the first set of levels.
This is a preview of the first level:

There was a thread for the SNES version awhile back. But I will be running on the Genesis version, as there's something like 4 or so fewer minutes of lag. Luckily the music level glitch where you can keep jumping up works in the GEN version as well,
One tricky thing I am noticing so far with optimization is the end of level marble scenes; unlike in the first Bubsy, you can't just walk into the goalpost with no speed to have no marbles spawn, and I am unsure exactly what causes fewer marbles to spawn; I do notice that when I jump into the marble instead of falling into it, fewer marbles spawn. Due to the level not ending until none of the marbles are in the level, it's optimal to collect them as fast as possible, but each marble does take a frame to count down at the end of the level.
