Works great, if you want all variations/betas on there get a 16gb sized card, otherwise 8gb is totally fine to have the ones you like from a certain region for eg.. the menu is great (if you tv supports it run go into options and run it in 640x 480 modeso oyu can see all the names in the dir list better) Almost instant loading of all games -Its the best money you could spend on an N64 (but dont forget the expansion pack and controller pack to complete the set!) after the os files are added to your sd card, it really is plug and play.
