About this game

My OldBoy! is a full-featured and super-fast emulator to run Game Boy and Game Boy Color games on the broadest range of Android devices, from very low-end phones to modern tablets. It emulates accurately almost every aspect of the real hardware. Special features including link cable, rumble, and tilt sensor are also supported. You can also make your GB games colorful by selecting a custom palette.

Of course it does not just emulate the hardware. Thanks to the save state system, you can save progress at any time and return back to it instantly. And while enabling fast-forward in game, you can quickly skip to the part of the game you are mostly interested in.

• Fastest emulation using ARM assembly code. Easily get to 60 FPS without frame skips even on very low-end devices.
• Very good game compatibility.
• Saves your battery as much as possible.
• Link cable emulation either on the same device, or across devices over Bluetooth or Wi-Fi, running at decent speed.
• Tilt sensor and rumble emulation through your Android's hardware sensors and vibrator!
• Game Boy Camera and Game Boy Printer emulation.
• Super Game Boy palettes emulation. Enhance monochrome games by bringing more colors!
• Enter multilined GameShark/GameGenie cheat codes and enable/disable them on the fly while the game is running.
• IPS/UPS ROM patching
• Fast-forward to skip long stories, as well as slow down games to get past a level you cannot in normal speed. Depending on your hardware, it can run as fast as 50x normal speed.
• OpenGL rendering backend, as well as normal rendering on devices without a GPU.
• Cool video filters through the support of GLSL shaders.
• Save games at any time with screenshot.
• On-screen keypad (multi-touch requires Android 2.0 or later), as well as shortcut buttons such as load/save.
• A very powerful screen layout editor, with which you can define the position and size for each of the on-screen controls, as well as for the game video.
• External controllers support, through either the Android native way or input method.
• Well-designed user interface. Seamlessly integrated with the latest Android.
• Create and switch to different screen-layout and key-mapping profiles.
• Create shortcuts to easily launch your favorite games from your desktop.

I think it's great! Seems like there's some negative reviews about some 'advanced' features people would like - maybe I'm just not that 'hardcore' but this has everything I need! You can choose your layout (portrait or landscape), customize where the buttons are on your screen, and play games. I just wanted to play Pokemon, being able to customize the screen and buttons was just a great little touch (that's probably taken for granted). At any rate, not sure what more 'advanced' features you could want... It plays Gameboy ROMs, and does it beautifully!

I was shot and killed by a swat team for pirating 20 year old games. Worth it. In all seriousness this app is great, definitely worth the $3.99 ($4.99? I can't even remember how much it costs). The controls layout being customizable is a huge plus, and the "cheat" code system is simple and easy to use. I hear its it's possible to do local online multiplayer, which I'm definitely going to have to try out asap.

The finest GBA emulator! I do have a couple of suggestions though relating to input: -It would be nice if you could change the buttons to be toggled. This would really help with platformer games; it is hard to run and jump at the same time. -I'd recommend allowing people to change the color of the virtual buttons. The turbo buttons in particular are red, which doesn't really show up well if you have blue-light filters enabled on your smart device. Overall, great product!
