The Freeloader works good and I play imports with it but there is a possibility that F-Zero won't be the last game with problems. Datel has not fixed the problem yet and I would like an upgrade if they do make a fix.
My dorm room is DDR central for my building and we have dance nights from time to time where friends get together to play DDR 7th Mix or the older mixes. Depends on who comes that night since different people have different DDR games. The Konami controller can get scratched up and dirty after a lot of sweaty feet have been dancing on it so I got one of these to keep the controller clean. Drinking beer can also mess up a controller since drunken dancing people can spill their drink and the cover guards against spilled drinks. I guess it can seem tacky or as tacky as people who put plastic slipcovers on the sofa or other furniture but I like to keep my stuff clean and sanitary. The cover fits my official Konami controllers but i don't know about the other ones that I see on Hong Kong websites. The nonslip thing is not important to me and I never had too much problems with the controller slipping because my room has carpet. It could slip on a tile floor but I never danced on that.
