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

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
8003f2ac ChangeState__5CGameFv stw r5, 0x0004 (r3)
8003f2b0 ChangeState__5CGameFv stw r4, 0x000C (r3)
8003f2b4 ChangeState__5CGameFv stw r0, 0x0008 (r3)
8003f2b8 ChangeState__5CGameFv lwz r4, 0x038C (r31)
8003f2bc ChangeState__5CGameFv mr r3, r31
8003f2c0 ChangeState__5CGameFv li r5, 0

8003f2d0 ChangeState__5CGameFv mr r3, r31
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

Thanks!!!!!!

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

Any ideas on how to shorten this thing? 64 lines as it is.

For starters, get rid of the 16-bit and 32-bit RAM Write usage for the ASCII String writes. Use the 06 Gecko Codetype (meant for dedicated String Writes) instead.

I have a question.
As the code stands, it rotates through the character values 0x0 -> 0x11.
The value for the Mii character is 0x13. It skips 0x12
I've been driving myself nuts trying to rewrite this:

lis r11, 0x8000 #ASM Load upper half-word of EVA address
lhz r12, 0x3b2 (r11) #ASM Load lower half-word of EVA address for interval timer.
lhz r5, 0x3b0 (r11) #ASM Load lower half-word of EVA address for character mod value cycling
addi r12, r12, 0x1 #ASM Add 0x1 to interval timer
cmpwi r12, 0x38 #ASM See if upper limit of interval timer has been reached; Adjust this for cycling speed
bne+ store_interval_timer #ASM if not reached, store the incremented value
li r12, 0x0 #ASM If it has been reached, load r12 to reset value to 0x0
addi r5, r5, 0x1 #ASM Load r5 to increment character mod value by 0x1
cmpwi r5, 0x12 #ASM See if upper limit of character mod value has been reached 0x11 (Black Mage)
blt+ store_char #ASM If not, store the incremented character mod value
li r5, 0x0 #ASM If it has been reached, load r5 to reset value to 0x0 (Mario)
store_char:
sth r5, 0x3b0 (r11) #ASM Store character mod value
store_interval_timer:
sth r12, 0x3b2 (r11) #ASM Store interval timer value
blr

How would I do this. I know this is going to be one of those "oh crap, why didn't I think of that" moments.

Thanks!!!!!!!!!!!

Nevermind. I figured it out:

loc_0x0:
lis r11, 0x8000
lhz r12, 946(r11)
lhz r5, 944(r11)
addi r12, r12, 0x1
cmpwi r12, 0x38
bne+ store_rotation
li r12, 0x0
cmpwi r5, 0x11
beq- skip_twelve

addi r5, r5, 0x1
cmpwi r5, 0x14
blt+ store_char
li r5, 0x0

store_char:
sth r5, 944(r11)

store_rotation:
sth r12, 946(r11)
blr

skip_twelve:
addi r5, r5, 0x2
sth r5, 944(r11)
sth r12, 946(r11)
blr
