After u have downloaded the unzipping program u can proceed to downloading an emulator. Head over to the emulator part of my site and follow the link and download the emulator. Once you have downloaded and extracted the emulator. You can start downloading roms. Roms are the actual games that u will play on the emulator . Once you have downloading a rom then you can start playing the roms. Open the emulator and go to the tab the says FILE then OPEN find the rom that you want to play click on the rom then go to open. Thats really just a complete basic layout of gba emulation. I realize that this isnt really well put or whatever but im not really number one in english class. well anyway if you are completely dumb or maybe you need a more thorough layout then please find another emulation explaining page. Thanks for at least reading this thing.
