Yeah, my private builds focus on compression ratio, using completely different compression algorithms. I designed it to be easy to depack. Figured theres no point in trying protection since people will crack it anyway. The public build is there so there is no real loss if people misuse it, although there might still be a possibility of that happening.

Pity the taggant scheme for packers is a crock of sh*t. (only useful for commercial stuff, not freeware) And digital signatures do nothing too.
Plus, many packers like ASPack, PESpin and mpress seem to miss crucial things like proper TLS callback support. I guess now I need to work out overlay support, and fully reentrant DLL entry points. (so it doesn't needlessly depack itself over and over)
Atm I am trying to debug a nice (as in, interesting and hard) test case with DLLs with TLS. For some reason there is one flaw there, but other DLLs with TLS callbacks work fine. Dunno if its something to do with reentrancy though.
