Two questions.

1) Can anyone tell me how to decompress the YI graphics? (Please don't say "Use Lunar Compress".)
2) Can anyone give the the formula or routine that converts a PC address to a Snes address and vice versa?

You could write your own routines, or, and I know you didn't want to hear this, but use Lunar Compress. It's easy. Here are all the compressed graphics I found for YI using sniff.
(Although I also posted this data in the Yoshi's Island Level Editor thread.. )

Yes, it helps me a bit, but I still need to know the decompression routine...
