I'll tell you a good reason... Easy drag and drop games to the SD Card. No install needed, no uninstall needed. You can easily find 'superxci files' that hold the game, all updates and DLCs (well there are 'supernsp' files as well you tell me.. sure there are but you still need to install them.yes they are, tell me a good reason to use slow XCI that can't switch from docked to handheld instead of nsp that load in fast microSD cards without having to go to a special menu to load them or any other special peripheral
SD card space. You need twice the space on your sd card (one to hold the nsp file and the same amount of space to install the game).
For me, dealing with games this way is easier as the console is shared by 2 of my kids. So thanks to TX for bringing this... but of course shame on 'em for fucking up big time with this update.
I sure hope they fix this quickly.
