Although there are some LZ77 compression sources
available, does anyone knows what kind of
modifications (or code) does these compressors need to
be decompressed directly to VRAM? (like the VRAM safe
option in the GBA Crusher) .
I know its related tot the fact that the compressed
data should not reference to the previous byte in the
uncompressed data because it may not have been written
yet by 16-bit, VRAM sized BIOS function.

Any help will be appreciated, thanks
