Code Patcher v1.0 [JoshuaMK] - JoshuaMK - 10-16-2019
Code Patcher v1.0 [JoshuaMK]
NOTE: Currently only working in Dolphin.
This code allows you to actively patch codes into the code list without needing to restart the game after applying said codes. Future versions may include deletion of codes, patching GCT files, scrolling to allow larger codes, and maybe even relocating codes when needed. But until I figure those things out, this is v1.0!
Disclaimer: I am not responsible for any screen burn-in issues caused by this code. If playing on a real Wii on a flatscreen TV, please activate the screen burn-in reduction option in the Wii settings, and only keep this menu up for ~5 mins at a time at most. As long as you deactivate the menu without injecting the code, your code will be saved in memory to continue working on.

RE: Code Patcher v1.0 [JoshuaMK] - Vega - 10-16-2019
Nice! Next up, GCT extender!
What is the purpose of the isync instruction for the C0 code? Have you tried the C0 without the isync?
On the ASM with the sprintf function, you should only need to allocate 0x80 stack space, not 0x90.
Also on the call_link macro, go to Stars thread on the Draw text, he's optimized the macro. You have the functions' first half address in a global variable register. Then do a macro with Ori, mtlr, blrl for both functions so the two occurrences of lis is not needed.
My current graphical codes (except Clock) use the old macro.
RE: Code Patcher v1.0 [JoshuaMK] - JoshuaMK - 10-16-2019
Oh cool. I had no clue. I plan to go over this code again with more optimizations, and features as the v1.0 implies. I will go over that for sure.
RE: Code Patcher v1.0 [JoshuaMK] - Vega - 10-16-2019
I responded to your PM.
Btw here's another optimization for note--
In the C0 ASM, I don't see any function calls. You don't have to make a stack frame. You can use the negative area of the stack instead. This will save you 2 instructions right there. I've been so lazy I keep forgetting to add that note in the About Register Safety thread.
EDIT:
went ahead and added that note to About Stack Frames thread instead.
RE: Code Patcher v1.0 [JoshuaMK] - salmon01 - 10-17-2019
This is awesome! I'm impressed.

However, I've seen various sources, and they only mention doubleword alignment as a requirement for ppc32. Might be the case or might not for the Wii-specific EABI, but I would be surprised if quadword alignment truly is necessary.
RE: Code Patcher v1.0 [JoshuaMK] - Star - 10-17-2019
Neat to see something like this come into fruition. It kinda reminds me of the exception handler Kirby Air Ride:

Ye there was some IBM Article for the PPC32 that states all stacks must be quadword aligned. Regarding the Broadway, I booted up MKW on Dolphin really quick and looked at a bunch of function calls, couldn't find one that was not quadword aligned.

Hey Joshua, here's how you can get Easy Extender to work... (the limit for display aka string lenghth is a lot less than Star/Riis code btw) So if everything is right and it still fails, you may have went beyond the string length limit. Or... YS's code is using some part of the Exception Vectors that you are using too, to get around that, just throw shit on the stack and increase the frame size accordingly... View some of star's complex codes to see how to save extra data to the stack for doing args for function calls
First, grab everything BUT the C0 code from the original Easy Extender - http://mkwii.com/showthread.php?tid=790 This will be at the beginning of your code.
So with this, you have two function calls available in an ASM code...
Sprintf:
lis rX, 0x8000
lwz rX, 0x1858 (rX)
mtlr rX
blrl
Draw Code:
lis rX, 0x8000
lwz rX, 0x1850 (rX)
mtlr rX
blrl
Next you will make a C0 code....
When you push the stack frame, do this instruction right before to backup the LR...
mflr r12
Once you pop the stack frame, do this instruction right after
mtlr r12
Args for the Draw code...
r3 = Pointer where data is (already converted from previous sprintf)
r4 1st byte = X coordinate (make this 01)
r4 2nd byte = Y coordinate (make this 02)
r4 3rd byte = font color (make this 02)
r4 4th byte = bg color (make this 01)
I use to have a list of ALL the color combos but wiped them by mistake. they may be on the wayback machine somewhere (when the site was mkwii.org)... if you care enough
ofc since you use the python compiler like me, you don't need to add the blr at the end for the C0 code.
I just did a test run for "hello world" with these guidelines and it works. So if this works for you, your code will for the Wii console on ALL games.
I tried doing this for my Mem Viewer code but I bypassed the string length limit by a mile, so there's really no point bothering with it anymore....
RE: Code Patcher v1.0 [JoshuaMK] - JoshuaMK - 11-19-2019
What exactly is the byte limit? Direct print allows up to 100 bytes.
RE: Code Patcher v1.0 [JoshuaMK] - Vega - 11-19-2019
Less than 100 for sure. Too lazy to narrow down the exact amount.
