>>28759880GBA games don't map to the screen resolution of the 3ds very well, since they run at 240x160 and the 3DS has a screen resolution of 400x240. If they just matched the pixels 1x1, the screen would be way too small on regular 3ds models. And even I say that not having restore points makes for a rough experience, what I'm really saying is that Nintendo doesn't want to put out games as part of the Virtual Console service that don't have the same feature set as literally every other Virtual Console games. Calling them Virtual Console games wouldn't even make sense since there's no emulation actually happening. Both GBA and DS games are out in the Wii U's VC, but not the 3DS, despite the fact that both consoles' libraries can be played natively. The only time they've done anything like that was when they added Wii games to the eShop, and in that case they refused to classify them as VC games. Nintendo cares about this stuff.
>>28759967If you play a lot of Sm4sh, get one. It's way better on a new 3DS, and they don't have to disable half the features of the OS to run it.
>>28759971They aren't necessary at all, but Nintendo aren't gonna put the games out there with them missing. Nintendo's weird like that.
