GBA emu is one of two Game Boy emulators here by Robert Broglia. This one is for the Game Boy Advanced. It comes with all the features you'd expect. That includes quick saves, BIOS emulation, cheat code support, hardware controller support, and even cheat codes. It is compatible with most game ROMs that we tried. It also plays smoothly. There is also cross-platform support with his PC version. That means you can play virtually anywhere. There isn't a free version to test. You'll need to test it out inside of the refund time to make sure it works for you.

Gemboy

GemBoy is one of the newer Game Boy emulators. This one covers Game Boy Color and regular Game Boy games. It comes with the usual set of features. That includes save and load states. It also allows for between presses for the A and B buttons. That makes things easier. Other than that, it's just a lightweight, simple emulator. It's a good option for those who don't want much between them and their game. It has a few bugs here and there, but it's an overall solid option.

MYBOY

My Boy is one of the most popular Game Boy Advanced emulators out there. It has a high compatibility along with a laundry list of features. They include superior link cable support (over WiFi or Bluetooth), high game compatibility, fast forward and slow down modes, cheat codes, and hardware controller support. It also has some advanced features like OpenGL rendering, BIOS emulation (so you don’t need a BIOS file), and rumble emulation using your phone’s vibrate motor. It offers an almost complete experience and that's impressive.

My OldBoy is easily one of the most popular Game Boy Color and Game Boy emulators. Much like My Boy (same developer), this one has a ton of features, including link cable emulation, cheat code support, hardware controller support, fast forward and slow motion modes, and more. It also includes the OpenGL rendering and rumble emulation like My Boy. In fact, it’s pretty much My Boy but for Game Boy and Game Boy Color. There's a free version to try. The full version goes for $3.99.

RETROARCH

http://lh4.ggpht.com/MFywT7QpnT6WA2vgh1Fb0bfaz2Si4BRCnWV53Hiu9lr1ZpE6tJ_mP7AmXzC7hy2wFFlD=w300-rw
is a multi-system emulator that uses the Liberto development interface. This system uses “cores” that you can install and each “core” is essentially a video game emulator. As it turns out, Game Boy, Game Boy Color, and Game Boy Advanced all have “cores” that work in RetroArch, making it possible to play all of them with just one app. It doesn’t have quite as many features as individually coded Game Boy emulators, but it has a high compatibility rate. It’s also totally free, open source, and there is no advertising at all. The only downside is that you'll need to learn how to use it. It's a big more complicated than other emulators.

Nostalgic gbc

Nostalgia GBC isn't as well known. However, it's still one of the better Game Boy Color and Game Boy emulators. Both the free and paid version allow for the same features, including turbo buttons, high game compatibility, and both on-screen controls and hardware keyboards. Unlike most, this Game Boy emulator includes a game rewind feature that lets you go back a few seconds to try a segment over again. It's fun to use, especially in platformers. The free version is ad supported and requires an online connection (no ads display while gaming, just during menus) whereas the paid version has none of these requirements.

John Gba

John GBA is easily one of the best Game Boy Advanced emulators. It supports pretty much every game out there. It also includes on-screen controls, game search, cheat codes, fast forward and slow down modes, and more. There is also Dropbox support for easy backups. That doesn't require another app called John DataSync. It works entirely offline and contains no advertising which is also a hefty plus. It’s relatively inexpensive and is a go-to Game Boy Advanced emulator for many people.
