Yer LZMA is a nightmare...
Just out of curiosity, how much temporary memory is used for the huffman
tree
In the version im reworking, itll end up needing about 32-64k
for dictionaries as well as about 8k for probabilities if i
use the full lzma system. Im altering it to be more Sam
memory size suited hopefully without reducing compressiong size.
I appreciate the challenge in making extreme

LZMA doesn't seem to be terribly well documented, but I'm curious so
do you mind if I ask a few questions?
The LZ77-style stuff is quite well documented on Wikipedia

Ok, providing I havent made any mistakes on the compressor it looks like
the sizes are down at:
1: 256 x 141 : 4416
2: 256 x 141 : 5613
3: 256 x 192 : 9103
4: 256 x 192 : 8594
5: 256 x 192 : 10103
Ill write the decompressor and check, depends how slow it is to
decompress i guess ;)
better compression rate.

They're 16 colour (quite poorly in one case), but not necessarily
using colours actually available on the Sam's. I've appended the
correct number of bits to store a Sam palette after the compressed

I've also discovered a bug that makes all my numbers worse. I'm
