Type 3 is some basic RLE encoding, type 4 is uncompressed, dunno about the others
edit: I use IDA Pro in windows, I doubt you'll have enough money to buy the full version of that (around $2k)
edit again: But you can grab OllyDbg or the free version of IDA
yet another edit: Looking at the VB/VH stuff did anyone try loading them into that psf lab app to see if they play?
