3DS?

It’s really good, but I wish you could play 3DS games on it.

5 stars all the way first off

But with one sidenote I been addicted to this it’s like having a little gameboy again but seeing it out for a couple years on iOS makes me crave more retro consoles was just wondering if any new old retro consoles are in the works for iOS love the app great stuff

Great emulator

Everything works great, except my 8BitDo NES30 Bluetooth gamepad.

My iPhone sees it, but the app doesn’t.

AWESOME

You need to get this because I used to play these games as a kid but you have to go on a website to download the files and import them to the app but everything else is good

Time for an upgrade

I give it 4 stars because I’ve had this app for years and I’m the description they claim “and more to come” as far as emulating other systems and that hasn’t happened yet. At this point it’s kinda silly that hasn’t been updated. How many more years do we have to wait before we can emulate another console? Emulating ps2 or original xbox really isn’t a stretch to achieve. So what is the hold up?
