Hey guys, I know this thread is a tad old, but I was wondering if you could help me out. I really like this idea, but I haven't had much success. Is there any way I can get some more detailed instructions for the RPi SD card setup? Any help is very much appreciated!

DJ Omnimaga

Heya and welcome here. :) I myself cannot help but hopefully @Streetwalrus might pass by and offer some, since he modded his Gamecube. In any case, good luck!

Setting up the SD card is pretty simple. You need to set up raspbian like usual then you can replace the kernel.img on the sd card with the one I attached (the compiled code).
If you succeed you should be able to boot burnt game backups or homebrew like Swiss and then boot games off of an SD card provided you have an adapter. GC-forever forums are full of gurus and that's where I learnt to do all this so I owe them this success and if you need more advanced help that's also where you should ask. ;)

Enaz

Thanks for your replies! :)
I'm going to try reinstalling Raspian, then replacing the kernel img. I'm also going to try some different media for my backups.

Streetwalrus

Cool. Be sure to give feedback, I'd like to know how well it works for you.

Enaz

Ok, so I've spent the past couple of days tinkering and still no dice. I've tried the mod on a couple different game cubes and tried different releases of Raspbian. By booting into Raspbian normally, I was able to confirm that I am getting feedback from the GameCube, because the data values of the connected pins would change when I turned the GameCube on or off.

I've attached a pic of my sd card setup. Any ideas on what might be going on?

I have no idea. The Pi-side pinout should be independent on the revision. What are you trying to boot ? Fyi the chip should behave just like a xenogc so try holding start on powerup with a disc inside the console (try an original first). Also you should hear the disc spin up, stop then start again during boot. The act/ok led on the pi itself should turn on to indicate it's working then back off. One last thing, the lid detector switch should be in the closed position or the drive will not initialize.

Btw the raspbian version doesn't matter as my "kernel" completely overrides it.

Enaz

Hey sorry I never got back to giving you feedback. I eventually determined that it was my soldering job that was to blame. The hack works quite well now. Thanks for the post!

DJ Omnimaga

Awesome to hear :D

Also I think Street :walrii: started doing Gamecube modding again a week ago.

Duke "Tape" Eiyeron

He has, he wants to make another thing with a FPGA or something.

How do I rig this up for the DOL-CPU-10? the one supplied is for the revision models I have the earliest one.

@Streetwalrus  might know how. It can take a while before he replies, though.


Streetwalrus

The motherboard shouldn't matter. You'll need to find different 5v and GND point for yours though. These should actually be on the DVD board as well. Probe around with a multimeter to find them (yes with power on).

And cool to hear Enaz. ^.^
