Yeah, pretty simple request. I know that the GBA link cable can send button inputs over it that a gamecube game can read since it's a feature of many GBA link cable games. So why not do this instead of requiring a GameCube controller? Amazingly, I don't seem to have one or if I do it's lost and I can't find it, so a solution that doesn't require one would be great and the most elegant and simple solution I can think of is to just let the GBA control things. Since... why not? Also hoping this project isn't dead, it's really awesome.

that would require some logic changes which I dont really feel like doing, I assume you are on a wii and use wiimotes? because I think for some reason I never added that, if you are I guess I can just add support for that instead for controls.

Fair enough, I went and got an after-market controller in the end. I'll leave this issue open in case anyone else feels like putting in a PR. I took a look into it and decided I didn't really feel like doing it either, haha. Yeah though, I'm on wii and I'd appreciate if you did add support for that for future wii users.

The gba link cable can't send directly the button inputs, but it's done by a "custom mini game" loaded on the gba memory that sends back the commands back.

So it's not a "pretty simple request" , but a complete rewrite of the gba code that needs to fit the communication part in just 256k ram. Not easy at all

Re: Wiimote input, I've started a fork with changes exclusive to the Wii.dol output file that should allow at least one connectable Wii Remote in the app to navigate alongside a GC controller, with mentions of optionally using their respective buttons on screen. I need to test some more, but for those who need to run this app on a Wii without Gamecube controllers, check it out.
