"Uses its own disk/tracksystem which is not compatible with the normal adf format or dms. Therefore it is stored as a .zip so far, containing 2 .scp disk images (40mb each) which are compatible with winuae (and can be copied back to Amiga disks via certain special hardware). Originally only possible to copy via its own embedded copy program - and only works on a mint A1200. Was spread on BBS's after The Party 1994 - but the dms files did not work due to the track system." - from Kestra BitWorld
