Jazz Jackrabbit Score Format
The high scores in Jazz are stored in the file HISCORES (It has no extension.) This is a very simple file 120 bytes long consisting of 10 12-byte entries. A default score table is stored in the executable and extracted if no score file is available. The score file is used only for certain versions of Jazz, notably Jazz CD and both holiday hares.
1 1 Name length. 2 8 Name, 'extra' characters aren't read, when the game overwrites one. name with another, it only changes what it needs to, leaving junk behind. 10 4 Score, stored as dword.
