Like the lz4 it"s a on the fly decompressor, so really fast but not with the better compression ratio.
I suspect that you may have a typo in your response ... I have yet to find a case (for 8-bit and 16-bit console/computer data) where LZ4 compresses better than Emmanuel Marty's LZSA1, let-alone his LZSA2 which does much, much better.
Here are optimized smaller-and-faster HuC6280 decompressors for the PC Engine to complement the standard-6502 ones of mine that are included in Emmanuel Marty's project on github.
Yes but it's also much slower too,in fact it seems that LZSA has multiple schemes depending on what you want, faster decompression but low ratio, or the contrary.
Yes, LZSA2 is about 20% slower to decompress than LZSA1, but then there is always a tradeoff between compression ratio and speed, or else we'd all use RLE for speed, or deflate for compression ratio.
The point is ... LZ4 compresses worse than LZSA1 and isn't any faster, and LZSA2 compresses much better than either (sometimes approaching aplib), and it is still fast-enough that you're unlikely to ever notice a difference.
I went through the whole thing with some LZ4 fans in a compression thread on AtariAge.
You can see an LZ4-vs-LZSA1 comparison here, and a size-test of various compressors here.
Please note that I continued to improve both the LZSA1 and LZSA2 decompressors after those posts, and they're both a little smaller and faster.
spenoza: So Power Golf and Lords of Thunder are too laggy to be much fun, but most of the other shooters are pretty sound, owing to being pretty damn responsive in their original form.

spenoza: All retro prices are up. Something about people being stuck at home and desperately needing stuff to do. It's why Netflix viewership is up and why Disney+ accidentally stumbled into the perfect launch window.

bigusschmuck: I suppose so. So much for a price crash lol

tron: yup same thing for blazing lazers/gunhed,digipiggy etc.It's getting rather insane for the sega saturn as well even commons for the console have skyrocketed in price.
