Bonk's Adventure (TurboGrafx-16)

Bonk's Adventure is infinitely better than its NES cousin.

Debug Menu


To access the debug menu, enter the following codes in Magic Engine at the title screen and press Run to begin a new game:

The first three codes set hex values at offset, a  which causes the game to jump into the debug menu as it's setting its hardcoded jump height and speed values when starting a new game. Specifically, it replaces, a operation for the speed value.

Once at, the game goes to a few other subroutines, and then to the main debug code at. Currently, there's no known way to reach normally (such as through a button cheat). It's located right after the code for finishing a round. It could use some more investigation to confirm if there's no way to access it without cheat codes/hex editing.

The final code isn't required to enable the debug menu, but is a handy fix to prevent the game from resetting jump height and speed to the defaults after clearing a round. It replaces with  at, causing it to branch over the reset.
