KHADIBAKH ($FF018C)

3DO-related menu text

As the 3DO version was released around this time, it's possible there was some cross-platform development or code-reuse, as the following strings can be found in the genesis ROM starting at $28944:

NB. Note especially "CTRL", "SHIFT", "ALT", "GAME 00-09", "LOAD", "SAVE", "TOGGLE SCREEN MODE" which are likely leftover from the DOS build, and the suspicious-sounding "3DO TEST" - however all the below can be found but is not actively referenced in the Mega Drive build.
