Debugging Context

A jump table is located at E000:4F4E (0x3E4F4E) and is called at E000:4E93 and E000:4EB0. The table is grouped by pairs of event pointers: init and update, which correspond to the 2 calls.

The Debug Menu state is index 1 (1st index being 0) within the jump table.

Hmmm...
To do:
Determine if the Debug Menu can be accessed without the use of a debugger, ie. search ROM for writes to 0x401 with the value 0x01 and go on from there...
