I had a 2002 version of UPX. Updating, I found they greatly simplified the commandline options (--brute is new), and it seems compression is also a lot better. But UPX does much better than zipping.

I don't have a USB drive, I burn CDs for large stuff (since it is generally things that I would like a backup of anyway), use networks, and occasionally floppies when windows dies or I boot into pure DOS or I want to use an old 486 I have lying around. > > I really don't see the point in spending a lot of time on this. Well, if anyone uses it they'd might like those utilities. If it's scrapped, I think we could still do with ohrrpgce_play, since a lot of OHR games come without (or with old builds of) Game, and the full distribution is quite large. > I'm sure UPX compression can be beaten by non-executable compression, > such as the free open-source 7zip.

OK, I tried out 7zip: Using game.exe at various UPX compression, and trying zip -9, 7zip (ultra, deflate), winrar (best compression) to produce .zips, and also a .7z: game.exe: 662,528 bytes zip: 258,250 7zip: 248,607 winrar: 257,933 game.7z: 182,914 game.exe through UPX --best: 208,384 zip: 204,933 game.exe through UPX --brute: 189,952 zip: 187,324 winrar: 187,165 7zip: 186,751 game.7z: 189,264 So UPX --brute shaves 70kb off the zip. 7zip did better .zip compression than anything else, but it was still way off UPX. I should note that UPX tries LZMA, the default algorithm for .7z files., while zips morely use the notsogood deflate algorithm.
