I can only vouch for Propeller Arena in particular having broken my list before. I'm not sure what it is about name.txt but one cannot simply make one for a game that's missing that file. It might be how it's encoded.
Honestly, while Madsheep's tool is a bit of a spank, I'd prefer a more optimized GDmenu that stores the gamelist in a TXT file on root. It'd also be neat to see that support individual folders. I'd prefer the idea of storing games in genre-specific folders, but I'm sure people would also like slapping games into letter trees. Maybe it works already, but I'm not interested in breaking my menu to see.
