The roms I tested were 007 Goldeneye, 1080 Snowboarding, Banjo-Kazooie, Banjo-Tooie, Conker's Bad Fur Day, Doom 64, F-Zero X, TLOZ: OOT, TLOZ: MM, Re-Volt, Resident Evil 2, Star Fox 64, and Wipeout 64.įor the TorrentZip test, the total file sizes were. z64 files were always smaller than the compressed. For both the TorrentZip test and the Torrent7z test, the compressed. You may be able to save a few more bytes using regular 7zip at the highest settings, but I prefer to use the Torrent7z format.Īnyway, the results of my test were conclusive. 7z formats using TorrentZip and Torrent7z. To test this, I took 13 N64 roms and converted them to each format using Tool64 (found here ). However, I wondered which format compresses more efficiently. If you had a copy of an N64 rom in all three formats, all three would be the same size uncompressed. Super Mario 64 has offset 00000020 look like this when converted from hexademcial to ASCII in each format: I won't go into the details of what endianess is (this is a "for dummies" guide, not a "for computer science majors" guide), but I think it'll be relatively simple to show what a snippet of a ROM looks like in these formats. These three formats contain the exact same data, but the difference lies in HOW they store it. There are three major formats for N64 roms.
