Title: Cruncher Request.
Post by: beb on 16:15, 16 January 18
Hi,


Anybody looked at this cruncher (Amiga executable and raw datas) ? Stronger than the last version of exomizer.
And requiring only 3kb of memory...

Arithmetic compression with a multiplication (16bx16b=>32b) for each bit, a Z80 version will be slow as hell

It's certainly not for (on the fly) AY register depacking... But for tiny things like 8 or 4kb stuff...
Still "slow as hell" on amiga. But one of the most efficient.
