Hi! I tested a few NDS games to see if do they work with TWLoader. I have no idea where to post these, but I suppose it will do here. I hope these are helpful enough!
Puyo Puyo Fever 2 seems to work semi-stable with a stutters, freezes there and there. It takes a few seconds for it to boot up, too. Cutscenes and things take a tad bit to load up, otherwise it's perfectly tolerable. Gameplay itself runs as smooth as butter. So it plays very much so like Puyo Pop Fever.
Puyo Puyo 15th Anniversary, translated and untranslated are quite the contrary. They won't load with a white screen.
Same goes with Puyo Puyo 7 translated/untranslated and Puyo Puyo 20th anniversary. The very same white screen.
I very hope so this was at least a tad bit helpful!
IMPORTANT EDIT:
Seemingly Puyo Puyo 15th Anniversary and Puyo Puyo 7 do boot up and launch with Puyo Pop Fever as a donor rom. It has no sound, black/white screens after pressing start at the title screen. Puyo Puyo 20th Anniversary remains at a white screen even with Puyo Pop Fever as a donor rom.
