Many of these can be sourced from Ralf's codes from GCforever here, but not all of those codes work on console, and some of them seem to have been written with different offsets from the copies of the game I have found online. Anything involving changing the compatibility of games worked on emulator but not console, unfortunately. In order to change that compatibility, the Universal Version of the game patch can be used (from here.)
Codes that I was not able to get working on console (like any of the region-free codes that attempt to change code in what's sent to the GBA) have been omitted.

had written to be changed with a press of L or R, but I never
figured out when or where to press them so I just made them separate codes LOL)
