The game contains a lot of debug text, starting at offset 0xC6370 and mixing with the rest of the game's text. Of note, two dates appear in the debug text that may be the dates the game finished development in North America and Europe:

North America: Jun 6 1997.21:45:51
Europe: Nov 17 1997.20:23:27

The rest of this submission contains a few examples of the debug text scattered throughout the ROM. Most of it is routine stuff, but there are some interesting gems in there. The developers were certainly not in a good mood or this was "kinda" a joke from them. Note that "tell dave" likely refers to David Pridie, one of the programmers:
