Developer: Tom Create Publisher: Bandai Platform: WonderSwan Released in JP: June 24, 1999 This game has debugging material.

Debugging Context

A jump table is located at 4000:47A6 (0x3447A6) and is called at 4000:45BC and 4000:45D6. The table is grouped by pairs of event pointers: init and update, which correspond to the 2 calls.

The Debug Menu state is index 0 within the jump table.

Set a breakpoint at 4000:44E2 and modify the byte at SS:101 (0x101) to 0x00 and continue execution.

To do: Determine if the Debug Menu can be accessed without the use of a debugger, ie. search ROM for writes to 0x101 with the value 0x00 and go on from there...
