Hum...I have some doubts about this too. Ive looked but found nothing related. Well, I've never used sneek. I've always used usb loaders nand emus for wiiware/vc purposes only. But i've noticed that so much games doesnt work if i boot them from these usb loaders. To live with that, I just install wads that doesnt work over the original nand (like rondo of blood, and other wiiware/vc games), so in one way or another, all games works.
-If I use sneek, the compatibility should be greter? I mean, the games will be loaded from usb/sd after all, in both cases (usb loaders nandemu or sneek nandemu).
-Shall I notice difference in performance if use with hdds from several manufacturers, or usb/sd, or just the loading times will be afected?
-I propably doing something wrong, cause i've looked around here in forums, that nand emus from usb loader has 99% compatibility for wiiware/vc...Anyone that mastered the use of nand emu in various ways can show us some light?
