ASM Activator/Deactivator For Dolphin [Vega]
On Dolphin the standard 2833/2834XXXX YYYYZZZZ' controller activator/deactivator lines do not work on older dev versions unless some Graphic Hacks are done via Graphics Config. Therefore in order to activate/deactivate codes, extra ASM must be written to the codes source. I decided to make this code for veteran ASM coders. At memory address 0x800015F0, the byte with value of 1 would be code activated, and 0 would be deactivated. Simply use this code, and then edit in the correct ASM functions on your current ASM code to read the byte value at 0x800015F0, and have the code activate/deactivate to that byte value accordingly. Obviously, you don't have to use that address, feel free to use whatever address you want for the byte value. Also, the base address of my code is constantly read by the game in all modes. It will instantly breakpoint at any time the game is running. This is needed because let's say your own code will have a base address that will only breakpoint when you grab an item box. Well if you don't use my code, you would be required to hold your activator/deactivator while picking up a box for activator/deactivator to take effect within your code.
