I just discovered something slightly funny: Apperently it is possible to add empty files to the zip file. I added a file called "b" And it worked... Quake 3 started.. as long as no other pk3 files present. I also tried truncating larger modified pk3 files but that didn't work. Maybe quake 3 arena demo only checks for correct file size ? Who knows ;) But my bet for now is on some kind of crc32 check... Maybe just the crc32 from the zipfile itself (though the sources indicate otherwise... some kind of special structure ? source code: "pack->checksum" ). I tried looking at the pk3 file with a hex editor maybe I should take a closer look sometime ;) Bye, Skybuck.
