I made a few simple modifications to my GameCube recently. I removed the dead CR2032 that was soldered in and replaced it with a 2 pin battery holder. This will let me easily replace the battery next time it dies. Next I replaced the fan with a Noctua NF-A4x10 FLX. This required a 40mm fan adapter plate and fan cable. The big mod was replacing the optical drive with the GC Loader PNP HW2 loaded with Swiss. This allows you to load games from a SD card instead of relying on the aging optical drive. I got a CARBY by Insurrection Industries for the video output along with a support brace. Lastly, I got a Retro Fighters BattlerGC Wireless Controller. Overall I am really happy with this GameCube setup.
Yep, pretty much.
Rocket Jump Ninja has an interesting take on the Mouse+Keyboard/Controller debate in Apex. I cant say I disagree with his conclusion, and I think he has some excellent suggestions.
