Extrems and Emukidid of the Swiss team has just released a few giant updates! One of the biggest is support for micro SD cards via an adapter designed by citrus3000psi that plugs into the bottom Serial Port 2 (on GC’s that offer the port). It requires a small, open source PCB that offers the same compatibility and speed as using the front port!

The main benefit is that it leaves the 2 front slots free for a memory card and any other peripherals you might require in games. Personally, I’d use it for games and use the front SD card for Action Replay booting; AR boot discs only support SD cards up to 2GB, however an easy work around is to boot into Swiss with a 2GB card, then swap it for a larger card filled with games and homebrew, then refresh Swiss. With this second reader, you can just boot to the 2GB card, then navigate to the second card after Swiss boots. This makes it really easy to run homebrew from an unmodded GameCube!

SD2SP2 boards will soon be available from Dan’s shop: https://shop.dansprojects.com/

The design files and BOM are available here: https://github.com/citrus3000psi/SD2SP2

This update also allows for better game performance via SD card, which at this point pretty much makes ODE’s pointless: Swiss + an SD card can be used on unmodified consoles and is a plug-and-play solution!
