Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FC8 – Faster 68K Decompression (2016)
I'm working on a game for Amiga (another 68k-based platform) and settled on ZX0 to decompress assets on the fly: https://github.com/einar-saukas/ZX0
I was originally using LZ4, but I switched to ZX0 after learning that it can do in-place decompression, which means I don't have to allocate separate memory for the compressed data. I'm very happy with the compression ratio, and decompression of large assets (~48kb) only takes a few frames on a 7MHz 68000.
Also of note is LZ4W, included in Sega Genesis Dev Kit (and discussed in the comments section of OP's article), a variant of LZ4 that only uses word-aligned operations. That makes it much faster on the 68000, which can struggle to efficiently handle 8-bit data. More info here: https://github.com/Stephane-D/SGDK/blob/master/bin/lz4w.txt
