I checked the gbatemp wiki for the YAOSM 3.2 firmware to find ALL firmware links dead, so here is the 3.2 firmware, i will also upload the 3.0 firmware which i found on my search for 3.2
it looks like you cant, not to my knowledge, atleast. if you really want, what you can do is configure usbloaderGX as a front end to nintendont, and set it to channel-display type. this looks similar to the wii system menu, and allows launching nintendont games
i think the easiest way to do this wouldn't be hacking the wii itself, but maybe hacking a wiimote? possibly an arduino of sorts, to read data from the wiimote and remap it to your hearts content
I'm not the best in the scene, but I'm no Amateur. I've lurked the forums for years, looking for help, learning, and now im finally ready to contribute!
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
