Debug Menu#

An unreferenced menu is present, but is missing setup subroutines, such as loading the font. This also leads to some graphical glitches, such as the current selected entry's cursor not rendering.

At 0x200800 there's a table of pointers to subroutines. We can replace an entry that is executed after starting a new game and entering your character's name, which already loads the required font for the debug menu. Apply the following patch:

0x810 = 51 7c 20

Event#

Loads various in-game events. Also includes a barebones but functional sound test:

Game Start#

N/A (Loads invalid data)

Send Striker#

These entries expect lowercase letters to immediately follow uppercase letters in memory. However, the font likely changed during development, and uppercase letters are instead followed by Hiragana and Katakana characters. If we copy 0x300 bytes from file offset 0xb1018 to 0xb0618, we have the lowercase letters at their expected memory offsets:

Receive AP#

This is likely a simplified test for the Neo Geo Pocket/Dreamcast Setsuzoku Cable accessory. A more featureful test is present but unreferenced by the debug menu. We can replace the subroutine for entry EVENT with the following patch (in addition to the one for the debug menu):

0x85ae = e1 7e

If this accessory isn't emulated, then when receiving data, status is WAITING, while attempting to send data leads to status TIMEOUT:

Debug DIP#

Another unreferenced subroutine exists that includes a second line to configure, but only the first line is actually updated. We can replace the subroutine for entry EVENT with the following patch (in addition to the one for the debug menu):

0x85ae = 00 7c

Yamauchi#

Input test. Holding any of the ABCD buttons fills the pattern of zeros with the button's mask value. The longer you hold, more zeros get filled. After some time passes, the values get cleared. The bottom values count Up/Down button presses.

Ito#

N/A

Shibata#

N/A

Watanabe#

N/A

Yosaku#

Booting the cartridge on a monochrome Neo Geo Pocket first displays the expected message informing the user that it is incompatible with that system. Pressing A on this screen causes it to load a remake of SNK's first original game, 1979's Yosaku. Help your woodcutter chop down the forest while killing boars and dodging the twin terrors of snakes and falling bird poop.
