Save Game Format (.CHR)

.CHR files are 'encrypted':

For bytes 0-0x1C0, XOR with (0xAC + file position). Then at position 0xF6 in the file is a BYTE indicating the number of opponents. The size of the opponents block (sb) = 68 * number of opponents For bytes 0x1C0-0x1C0 + sb, XOR with (file position + sb - 0x1C0)

Once decrypted, the contents of the files are as described below (from raptor's post here: http://www.omf2097.com/~forum/viewthread.php?tid=14)

NOTE: Im not sure what happens when you choose values other
than these, but I think it just assumes the default
color for the current pilot.
