One thing to remember though is that some games (eg. Parallax or Lemmings) use different formats invented by *cough* yours truly, which the suggested format won't actually be able to support. This includes: Sector addresses which do not directly correspond to their real location on disk - eg. on track 4 you'd have a sector which had a sector ID of 10, and a track id of 255. (This happens in the Parallax copy protection). Lemmings includes large storage disks (again, one of mine) with (IIRC) a similar scheme for sector address munging. The trick is that it used 5 x 1024 byte sectors followed by 1 x 512 byte sector to fit 11k per track, instead of the usual 10k. I think it may also have written 82 tracks. Not sure though. Any truly generic archive format would have to support such disks. Simon
