Finally got around to opening and checking out the BittBoy I received weeks ago. So far, I like it much better than the PocketGo. That screen is really nice, and I don't notice any light bleed with it. There's a little scratch in the black bezel where light comes through, and that's annoying, but for the price point? I guess that's to be expected. Side by side, the BittBoy feels like a better build than the PocketGo. The NES emulator is still shit, which is too bad. Everything else that I'd expect to be playable is, though. I'm not really expecting much from SNES and up.
A volume wheel would be nice. You can change volume to a few presets with select and A or B, but you're stuck with those set levels with nothing in between. I'm also not sure about the form factor, as far as comfort goes. Maybe I just hold it weird, but I couldn't play this for long stretches.
