For pure EXE crunching i would rather use "CrunchyDat"
http://aminet.net/search?query=crunchydat
It's giving usually better ratios than CrunchMania and the decrunch header got no cache flush issues on 68060 CPU's unlike CrM.
It's very fast, very easy to use and even ur beloved $dff180 flashes are included by choice.
But beware the unpacked file will be overwritten with the crunched one, so always use a copy.
For data crunching and special features CrunchMania is still the tool of choice.
And the trial version 1.91t is good enough for these purposes.
U can still go with the real old skool crunchers like ByteKiller 1.3.
But for what reason?
