With Gamecube/Wii there is code stored within dol memory locations, and we can actually edit and add to this compiled assembly code within memory with the use of gecko/ar codes. And this page will detail on how to make said codes with help of the documentation from BannerBomb. Now, to make a gecko code with the code types below dolphin debugger is recommended for looking at the compiled c++ assembly and experimenting with each function.
			and to make a code first grab the base address that you want to inject into and put what ever code type as 80 or 90, like for example lets say that the base address that we want to inject into is 800021c0 and the code type we want to use is 04 32 bit write to ram. the memory address would become 040021c0 and the second part of the code represents a instruction with its registers and parameters. like lets say that we want to insert a NOP to 800021c0 that code would look like "040021c0 60000000" which 60000000 being what represents the NOP instruction.
