For one, you're a bit late to the party there. For another, why the fuck would anyone NOT mind that question in this context? Calm down. Not all of the work was even yours in the first place. Also, it wasn't presented as "new," it was presented as a rounding-up of all the info we have.

I never claimed I owned these patches, or that it's "all new", and I told you explicitly before that I was going to archive everything you did in one place.

And no, I don't have autism, but I do have some depression.

Quick question: Does anyone know anything about region porting?

For example, I want to port Shadow the Hedgehog from PAL to NTSC-U.

The PAL code is:

04585194 3FB00000

I locate the address 04585194 in Cheat Engine but nothing appears.

We're really lacking in the "documentation department" and there's like, no tutorials on this.

The first value, the address, will never be the same for different regions. So you will have to search for the second value, which does control the aspect ratio or width in most cases. Since GameCube and Wii games use Endian to store values you will have to restructure the "3FB00000" to "0000B03F". Use this to convert from hex to little endian.

Note: I myself couldn't ever find the same address and value with cheat engine that a AR code actually changes. Dolphin is different from PCSX2 so you can't just search with Cheat Engine and make a AR code out of it. We need future infos.

Edit: There is documentation, you just have to read your own thread. Check post #5 which contains links to learn almost everything you need.

Hey gamemasterplc, do you make these codes yourself? If so, could you explain us how you do them?

[gamemasterplc]

Its Not Easy. Here's something you can try for 3D games.

Step 1.
Open Dolphin Debug Mode

Step 2.
Search for a 32 bit value of FFA01090 in the Cheat Search included with Dolphin.

Step 3.
Set a execute breakpoint on the addresses found until one is constantly executed when 3D is displayed.

Step 4.
If one is found that executes when 3D is displayed look at the function that called it for loads to f2 right before the call.

Step 5.
Try writing 40000000 to the address to see if the view has gotten wider. If not write a function that multiplies the float in f2 by 4/3 and moves it to f29 at the address that is constantly executed.

FFA01090 decodes to an instruction to moves f2 to f29.
Not all games work with this method.

Thank you so much!

Quick question: what does the second line do? I know the first line is FOV.
