Extracting data from cartridges

Anybody here have experience in removing the data/image of a game from actual game cartridges for gameboy advance? Any tools I can use or can you point me in the right direction so I can do this myself. I'm looking to make a backup of one game I purchased. I've seen it here in TOC, but that particular game is in Chinese type language, not English (or option to change language) the cartridge I have is in English. Thanks for reading!
