GC2SD 2.0 Upgrade PCB
Replacement upgrade PCB for GC2SD sold on aliexpress/amazon etc to V2.0 for use on GameCube's Front Memcard Slot B
Based on the SD2SP2 2.0 made by Extrems, Thank you for your hard work!
Important
When using the adapter make sure to have the Latest Version of Swiss, Due to the way Swiss handles it in SLOT A it acts like a normal speed Passive SDGecko, in SLOT B it works in Semi-Passive 2.0 enhanced speed mode.
