general bugs:
old input no work
song position is bugged 
accuracy petty bugged as well

improbable outset:
pretty good, the background is a little weird along with trickys animation

madness:
basically, the same,  background is weird along with hs animation

hellclown:
huh, tricky you look different... you get a haircut? (tricky is pixilated and clipping madly lol)
hank is just fucking floating
bf has gone 4-bit
also, gf is gone
charting is weird and no bad notes?

expurgation:
no bad notes, charting is weird and the background doesn't fit at all

overall, good port!
