I’ve been using John GBA for a couple months now. It’s basically a GameBoy Advance emulator for Android, so you can play all your old school GBA games on your phone. Pretty solid app if you’re into retro gaming.
Here’s what you can do: there’s a ton of features like cheats, high quality graphics, Bluetooth controller support, and even Dropbox syncing. It’s got a built-in keypad so you can play right on your screen. And the fast forward/slow down option is super useful when you’re grinding through levels.
Look, if you’re a GBA fan, you’ll probably love this. It’s not perfect – the UI can be a little clunky and it took me a while to figure out how to load my own game files. But overall it does a great job of emulating the GBA experience. Worth checking out for sure.
