I don't know how long you've been testing Homebrew Adeka but both these statements are wrong. I'm not actively testing Ningendont at the moment but I've been on the scene testing DM, WiiFlow, Devo and several other homebrew projects and loaders and compatibility is never the same across all users it's practically impossible, there's different conditions & there's different hardware as well as the possibility of the performance being different for the same type of hardware.
If it was that simple and all users experienced the same end result we wouldn't have to test as much as we do and make as many revisions and reverts as are needed in development. Same thing goes for the loaders, Cyan has needed to update USBL-GX a few times already to be compatible with some config changes in Nintendont. Same goes for WiiFlow so loaders have a definite affect on the outcome launching a game. CFG works differently so it's possible it hasn't needed an update so it doesn't affect you.
Anyway hope I don't come across as rude, just trying to be informative, your results are not definitive otherwise we would not need beta testers. Please be patient & stay be a bit more open-minded when it comes to others results.
