This area is dominated by the GBS-DOL chip which on one side connects to the Gamecube port and on the other to the pins of the GBA CPU. The interface takes up the job of communicating between the Gamecube and the GBA CPU. There also isn't a clock crystal directly connected to the CPU - more on this later. The board naturally lacks other normal GBA components such as the screen, buttons and speaker.

There's a supporting SRAM chip, link port and of course the game slot. The CPU (marked CPU AGB A) on the bottom of the board is the same as the CPU in the original Gameboy Advance. At the back is the Gamecube connector/interface, at front right are various voltage regulators and lastly at front left is the CPU and ancillary components. There are three main areas of interest on the board. They may not work if repeated on other board revisions. I've seen photos of boards marked DOL-GBS-01 and DOL-GBS-10 which are slightly different for this project I'll only be describing information and modifications for the DOL-GBS-20. Opening up the case revealed a single PCB, shielded with metal casing.

It connected via the accessory port and a boot disc provided the software to allow the Gamecube to interface with it, providing control, video and audio output.įor my project I'm working with a European (UK) version. The Gameboy Player accessory allowed Gamecube owners to play Gameboy Advance, Gameboy Color and Gameboy games via their console.
