Debug Menu

Please elaborate. Having more detail is always a good thing. Specifically: Can this be cleaned up/rewritten for an audience that may not understand assembly code?

This menu would have appeared in page 5, but it's prevented from loading. Function 00000490 reads the page from its I/O data address, but when the index is 5, it's overridden with index 6:

000004ee 0c 47 00 05     cmpi.w     #0x5,D7w
000004f2 66 04           bne.b      LAB_000004f8
000004f4 3e 3c 00 06     move.w     #0x6,D7w

We can turn the above override into a no-op instruction with the following patch:

000004f4 = 4e 71 4e 71

Most menu entries are used for loading specific mini-games / scenes.
