What is a GBASKIN file? File used by GBA4iOS, a Game Boy Advance emulator for iOS devices; contains texture data that customizes the appearance, or skin, of the Game Boy Advance controller used to play games on your iOS device; similar to the .GBCSKIN file.

More Information To change skins inside the GBA4iOS app, select the gear icon in the top-left corner, go to the "Controller Skins" section, tap "Game Boy Color" or "Game Boy Advance" (depending on which skin you want to change), select either "Portrait" or "Landscape" (depending on the orientation you want), and select the skin you want. NOTE: You can download GBASKIN files through the GBA4iOS app. You can also download skins from Game Boy skin websites and manually import them into the app.
