Not sure if you are still interested, but ive tried this:
NES-SNES-GEN-TURBO16-MULTIBOOT-Wii-NTSC-USA
Which i found on usenet and basically someone has pre-compiled the iso, complete with USA games from all those systems, even master system which it does not list in the description.
Anyway, it works really well, and has the option for 480p, so give it a try, they look really good when compared to virtual console.
Well my VC runs at 480p and I have it stretched to 16:9 and it looks great, but obviously I don't have quite the rom list that I do with homebrew.
I have a Q though. I have this same disc and I cannot get these Emu's to display 480p... In the GCOS boot screen it asks me to hit 'Y' for NTSC and 'R' for 480p, among a few other options. No matter what I select I can't get it to display 480p, it is only 480i (which my tv lags at). I of course have my wii hooked up with component cables...is there a trick to this? What am I doing wrong???
