Run some tests and see what you find. That's what I'm gonna do when I return to my PC.
Please note that FreeArc is an x86 program, so in order to use the x64 CLS variant, you will first need to use some kind of wrapper such as wrapcls by 78372 or FAZip (not FAZip32).
It's gonna be a lot of fun to play with. A cls is what I've been secretly wishing for, thanks Razor
