Lord Monarch: Tokoton Sentou Densetsu
Developers: Sega, Nihon Falcom, Omiya Soft Publisher: Sega Platform: Genesis Released in JP: June 24, 1994 This game has debugging material. This game has a Data Crystal page

A pretty solid port of the early RTS (as in "the original PC version predates Dune II" early) entry in the Dragon Slayer franchise. They really couldn't seem to decide on a consistent genre for the series, huh. This version of the game adds a story mode alongside a neat graphical facelift.

Though it, like most Dragon Slayer games, never left Japan, a fan translation is available.

Disabled Error Handler

To do: Figure out what the values mean and how the numbers are separated.

The game does have a debugging error handler, but it's disabled by default (the game will reset on error). To re-enable it, hold down A+B+Start on controller 2 during startup, letting go only after the Sega logo has started. After that, a crash will cause the game to reset into a dialogue screen that prints out basic debugging information three lines at a time (use the controller buttons to cycle through; the game will restart when it's done reporting information). (An easy way to test this would be to use Gens/GS, where Ctl+Backspace swaps the bytes of the current instruction word, which will usually result in an error.)
