☰ Overview

MeBoy is a pre-smartphone Gameboy emulator, allowing mobile phones to play Gameboy games. It was written for phones using Java Micro Edition (specifically MIDP 2.0), which was popular in the days before iOS and Android.
MeBoy supports both Gameboy and Gameboy Color games, and with version 2.0 you can even play your games with sound! With MeBoy you can also save your progress at any time, whether the game itself supports saving or not. Any number of saved games can be stored concurrently (only limited by your phone's available storage space). Since version 2.0, you can share your saved games with your friends via Bluetooth.
I started working on MeBoy in 2005 after I wondered why there was no way of running Gameboy games on my (at that time) new and shiny mobile phone. Determined to rectify the situation, I started work on MeBoy by porting JavaBoy (archive.org snapshot of now defunct website) to J2ME (JavaBoy is a Java-based Gameboy emulator for PCs, written by Neil Millstone). The direct port could only emulate a single frame per second! Lots and lots of optimization later, MeBoy was ready for release.
Development continued until 2009, when new generations of smartphones that did not support Java ME started taking over the mobile world.
If you can't get MeBoy to work, it's most likely due to one of the known issues, or else covered by the frequently asked questions. Unfortunately, there's no additional support provided.
