A GBA emulator is a software program that allows you to play Game Boy Advance (GBA) games on your computer or other devices. Emulators work by mimicking the GBA hardware so that the software thinks it is running on the original hardware. This allows you to play GBA games on your computer without having to own the original console.
To use a GBA emulator, you will need to download the emulator software and the ROMs for the games you want to play. ROMs are digital copies of the original game cartridges that you can download from various websites.
There are several GBA emulators available, including VisualBoy Advance, mGBA, and BatGBA. Some emulators may require additional software, such as BIOS files or plug-ins, to run properly.
