yes, its very good, that megadrive-joysticks could be used. i have some 6-button arcade-joysticks for it. even c-64 and amiga sticks should work, but they only have one (or sometimes two) firebutton(s). but, for example SONIC THE HEDGEHOG needs only one.
some customers dont gave good ratings to this console, but i read them and they all just give ratings in comparison to the WII. nobody rated the mega-drive-compatibility and i think most people just dont know anything about the possibilities they would have, when owning this passport-sd-card-module (because of playing roms)
for people who dont speak german, here are the google-translated sites to the products i mentioned above:

maybe i do (especially because of the passport-module), than i have 4 megadrives *LOL*
