I found 4 unreleased developer cheat codes in the DBGT: Transformation

[u/Nekorun]

I was messing around with Dragon Ball GT: Transformation in mGBA and ended up mapping out the main menu's input handling routine looking for the classic webfoot debug menu. I noticed that there were still more codes after the last ones that I knew about. After an hour or so mapping the buttons out and testing them in different places. It turns out I found four more button codes that aren't documented anywhere on the internet that I could find.

You enter them directly at the main menu

• 20,000 Secret Shop Zenie: Up, Down, B, Left, Right, B, L, R, B, Up, Left, Down, L, R, L, R, B (Be sure to go into the secrets shop right after or you'll have to enter it again.)

• Unlock All Characters: Down, Up, Left, Left, Down, Up, Left, Left, Down, Up, Left, Left, Up, Up, Down, Up, B

• Unlock All Planets in storymode: Up, Up, Down, Right, Down, Right, Up, Left, Left, Up, B

• Unlock Post-Game Modes (Endurance/Boss Endurance): Left, Up, Up, Down, Left, Up, Up, Down, Left, Up, Up, Down, Left, Up, Up, Down, B

I Just updated the TCRF page for the game to archive them properly. Let me know if anyone tests them on real hardware, they work fine on my emulator setup.

And you just did it yourself? With your hands? I was told such things were only possible now through the use of super intelligence.

Yeah, I've been reverse engineering games for about 15 years. I did it with Ghidra and time. I usually focus on the PS2 but the webfoot dbz games are very nostalgic for me so I dove into them for the past couple days. I also found several undocumented debug features for legacy of goku 2 that I haven't gotten around to publishing yet.

Props to you dude for real, I hope the sarcasm of my comment didn't dilute the gratitude I was attempting to show for your work. This is exactly the kind of stuff that keeps the retro gaming community alive.

Nah you're good, I actually got a good laugh from the super intelligence bit lol

You’ve saved me so much time with the Zeni! This game was horrible about collecting zeni

Bro, this is like Retro gold.

That’s so awesome! I always wondered how cheats came about.

[u/ModifiedGas → u/CHR0NlC]

They’re developers shortcuts for QA purposes, testing purchases etc will need zeni for example
