Whether it is home or portable is irrelevant, it is all about the hardware itself. It wouldn't matter with a console, there'd be no difference between console and handheld, but a handheld would have a more difficult time emulating a home system if the display resolution of the handheld is smaller than the original system.
This is why we wont see home consoles on the 3DS virtual console, right? I would prefer that they just kept the two seperate and offered each a uniqe arsenal of games.
What does a virtual handheld service mean for the wii virtual console? If Nintendo is going to offer VC for a new system, they will have to push it into the main stream and this must mean that they might speed up the wii virtual console once again.
I have a strong feeling that Game Gear and Neo Geo Pocket color games are going to show up on the service. I keep saying it, but I think the slide pad on the 3DS could accomodate NGPC because of the similarity with its D-pad.
I would love to be able to play all the older Nintendo competitor handhelds without having to worry about batteries or back lighting.
