This is a pretty cool project.. And the wii is fine for old school gaming.. I collect arcade games and mod game systems as well.. And my project would be to make a nice Mario Kart Arcade GP cabinet.. But thinking that using Dolphin and a decent pc might be the best way to go about doing the project the best way.. But again, not having true steering wheel fighting and feedback takes away considerably from the experience.. I have Hydrothunder in my house, along with MK3, Area 51, Ms. Pacman, Raiden and a 60 in 1 cabinet.. I would love to have a MKAGP for sure..And my wii plays them fine with quadforce.. But would love to have the higher res to go along with the machine itself..
