In a previous edition I wrote up how to access debug menus in a few Saturn RPGs. Let’s do it again! Here are three more games with hidden debug features:
As before, these would likely be useful for translating these games to English. If you’d like me to share my reverse engineering notes on them, send me a message!
Grandia Digital Museum
I thought this was a demo disc, but it’s actually its own game. It’s very similar to Grandia, however, and that game’s debug mode is present.
Quoting TCRF, the change to make is:
Debug mode can be activated by editing the contents of the file DEBUG.BIN in the BIN directory on the Grandia CD, and changing G:0000 to G:4000.
Press Z+Start to cycle through the menus, and hold Z and the D-pad to make selections in them. The features are more or less match the main game’s, but what’s cool here is that you can jump directly into the minigames from this screen:
Get the patch from SegaXtreme.
Shinsetsu Samurai Spirits Bushido Retsuden
This game checks a flag at boot to determine whether to launch the debug menu. The flag lives at 00200028, and the patch to to skip the check for it is:
06010926 e100 # Read a 0 for the "debug disabled" flag
060118ec e100 # DittoA few items don’t work: Live Tour, Chr Test, and Sound Test. For what it’s worth, I also got this menu working on the PlayStation version and they didn’t function there either. The Neo Geo CD version didn’t seem to have this menu at all.
The other items do more or less what you would expect based on their names. BG Map Test is nice; it lets you navigate the different background images. Press L and R to switch maps; Y to toggle display; D-pad to move around:
Debug Switch is particularly interesting. Press Start to bring it up after selecting it.
You can get a patch to enable this menu from SegaXtreme.
Marica: Shinjitsu no Sekai
This game’s debug mode is activated with a cheat code:
- Go to the Option screen.
- Without touching the BGM item, go to the bottom item, hold L+R and then press X. You’ll hear a sound.
- Increment the BGM item, then go back to the bottom item. Hold L+R and then press Y. You’ll hear the sound again.
- Increment the BGM item again, then return to the bottom item one more time. Hold L+R and then press Z.
The debug screen will come up. Here’s my translation of the top level menu:
The FIELD TEST item will transport you to arbitrary locations.
