So, I did stuff at Stage 8 boss. Hopefully it's a better show. One key problem is that, somehow, an entire stage later, I get a desync at stage select from an extra lag frame in transition.
I had no idea this was possible. Anyone up for some deep analysis in the functions?
One could also try to take pieces of the older and newer movies. It's a good bet I left intact the exact positions of where I released each charge shot, so direct copies of antics between shots might work.
