[REQUEST] Gotcha Force - Quick Level Gain Code

[shabbywizard]

Can someone make or convert a quick exp gain code for Gotcha Force NTSC-U on the Gamecube?

These are Wiird Codes for the PAL version of Gotcha Force.

Ralf sent me this information to port the experience code but I don't know how to do it. Can someone who knows how to do that use this to find the hook address for the NTSC-U version of Gotcha Force.

Message:

the EXP Gain Modifier code is relatively simple to port, because only the NTSC-U hook address of the C2-code is needed.

PAL hook address = 0x801CE31C

With the help of the little ASM dump above, it should be no big deal for you to find the correct hook address for the US version.

Thanks everyone for the help.

I realize this is a significantly old thread, but I wanted the code for personal use, and I believe I've done it correctly. The address in the US version is 801CCF64. I'm very unfamiliar with how AR codes work, so I'm not sure if I did it correctly, but the modified code is working on my Wii. And I'm sure the multiplier can be adjusted just like Ralf's.

Here's the Wiird EXP codes for the US version.

Quick EXP Gain
C21CCF64 00000002
831A0008 1F180005
60000000 00000000

EXP Gain Multiplier
C21CCF64 00000002
831A0008 1F1800xx
60000000 00000000

xx = Multiplier

Huge thanks to Ralf and Shabby for providing everything! Since it's a simple edit of Ralf's codes all credit should go to him.
