Unfortunately the method used for [[region detection]], testing bit 6 of the value read from I/O port $00, only works on the Game Gear. On the Master System, reading this port is usually unsupported, but happens to return different values on different hardware revisions of the Sega 8-bit family.

The game therefore does not show "TM" when run on an original SMS. "TM" is displayed when run on an SMS 2, a Game Gear in Master System mode or a Genesis with Power Base Converter.
