The only thing that could do well for the X7 is it had the capacity to play Super Nintendo games.
Dude, no. Everyone's so weirdly demanding for emulation lately — which I can't understand in the least because as far as I'm concerned the whole point of using flash carts is to avoid unnecessary emulation.
Now as for a possible X7, it's got to do one thing and one thing only to grab my interest: be the same size as a standard GBA cart.
That hump may be acceptable with some console versions, but it looks and feels like crap on the Micro. I don't care if an X7 picks up save states or any other new feature — if it's still the same size as the X5, it's not getting a second look.
