Well here's a teachable moment. Hopefully you can walk me through calling the following function.

In the symbol map I found a function: AddDebugWeapons

At no time during bootup or gameplay is this function called (Using BP on 0x80041768)

Here is a little blurb of the function that has the only branch that will take me to AddDebugWeapons.

There is no conditional/non-conditional branches in the map that takes me to: 8003f2c8 ChangeState__5CGameFv cmpwi r3, 0
At no point, does a BP set on 0x8003f2c8 trip during bootup/gameplay.
The change state function takes place when entering or changing areas.

8003f2a4 ChangeState__5CGameFv addi r4, r4, 21581
8003f2a8 ChangeState__5CGameFv li r0, 0

8003f2d4 ChangeState__5CGameFv bl ->0x80041768

So how would you go about calling the function?

I used this:

lis r12, 0x8004
addi r12, r12, 0x1768
mtlr r12
blr (and also blrl)

I tried this: momentarily turning it on/off with a C0 code, but the game just crashes.

Does this need to be an inline assembly (C2) code? Hooked to something like a change in the options menu etc...

Here's the button activator for the game: 28444d00 0000XXXX

I'll try to keep this as concise and to the point as possible.

1. Instead of posting entire functions, its better to post their names with their args and return values.

2. Some functions depend on a return value from a previous function. Let's say we have three Functions. A, B, and C. You call A with an initial argument to ask it perform a certain task. If the task completes successfully, function A returns a value that you need to use as an argument for function B. You Call B with that value. Function B then returns you a new value. That new value is needed for Function C. You then call Function C with value. This can get pretty complicated especially if Functions have their own child/sub functions that need their own values that must be derived beforehand.

3. When to call a Function in within a code? Use C2 or C0? This depends greatly. Like in MKWii, some functions are only meant to be called during a Race. Thus a C2 code using a hook address that only occurs during a race would suffice. Trying to write a Code to call it outside a race will end up in an Exception ofc.

4. If you are able to call a Function in C0 (usually it's a generic function like a file handling thing), you may need to disable interrupts.

5. blr/bctr is to have the function NOT return back. This is usually only suitable for functions like Shutting Down the Console. Other functions need to be called with blrl/bctrl. The return address will get saved in the Link Register. Function can return back.

6. Have a better understanding of C/C++ to understand how the game operates on a higher level. This will also give you a better understanding of how functions work on a lower level (Assembly)

7. Conclusion: Read the following two threads completely. If you have already read them, read them again. Another idea is to search on this forum for Codes that include Function Calls. Read over their source(s), that can give you some pointers/tips
