Identification
v≤1.1 EXE: ASCII "erawtfoS MJ" (read it backwards) appears somewhere in the overlay segment (refer to MS-DOS EXE#Special file positions), apparently at some multiple of 512 bytes from the start of the file.
v1.2-2.0 EXE: Undetermined.
v2.1-2.3 EXE: The overlay segment starts with ASCII "SQWEZ v2.".
v2.1-2.3 SQZ: The file starts with ASCII "SQWEZ v2.".
