Not this oneNah Gecko is a bit o homebrew what makes my Wii play other region games. Sadly, it would seem that my new Kirby (full of old games mind you) seems to have it pegged. I can get it running with a bit of option messing about, but it's unstable, I guess that's understandable though, as I noticed the program hasn't been updated since 2010!!
On the plus side, the 20th Kirby pack is pretty cool. Not as many retro games as the Mario pack, but there is a kick arse museum mode and you can view 3d models of the Japanese game boxes and some Kirby manga. As well as READ the manga! SAWEEEEET! As well as videos of ALL kirby games and stuff as well. It's a pretty great little pack and well worth the $40 considering the history and stuff in there.
