See this old ESP compressor Github
repository and get the "image24.raw" file...
The declared name "MM2" filter from 24bit images, better than LOLZ used versions? (ESP compressed to 333 bytes.) Classic LZMA wont compress in below 60+ KB sizes. LOLZ in get barelly smaller output.
Code:
69 519 image24.7z
72 493 image24.dlz
2 610 image24.lolz
98 304 image24.raw
I wonder if it would make sense to create an extended data filter based on this "MM2" algorithm—perhaps in the form of a standalone compressor and/or CLS filter?
