can you link to that new hack then? the last version of it i have didn't have that fixed yet.
the stages he did may seem interactive, but they're only a shoddy hack, the interactive stuff has to be put into each character's code/sprites to work.
edit: got it and tried. it's permanently locked at double resolution (i don't want that, my game is particle heavy and entirely done in low resolution anyway) and where it played fine in my old version it lags here. sorry, but it's useless.
