I didn't have much money back then, still don't have a whole heap. What I had then was soldering skills, and now I have a bit of digital design knowledge as well. Hopefully, this means that I'll be able to help with any problems that may crop up.

I'm still really interested though. Good work on the ...

I CAME BACK!

Not much to say - just that this project seems to have come a little further, and now that I've had a couple of courses in VHDL under my belt (as well as digital design), I feel a little more confident in my ability to help. At the very least, I now know who I can go to in order to get ...

Can do. Exams right now, so nothing for a week or so at the very least. And that's a big if - I'm not taking on the commission unless I know I can do it, and at the moment I don't know if I can.

Is there a method for booting of an SD card without involving the disk drive? As you may have guessed, I'd like to eliminate the drive to save power and size.

I read a while ago that you could use Qoob and GCOS, but I couldn't get any good details on it.

I've been considering it - there were images of a so-called "Gamecube Portable" that kept going around the web. I'm about half way along myself. If things go well for me, I may take on your commission but I'm not promising anything yet.

Suspicious... SATA is heaps more complicated then SD access. Much higher clock and data rates, not to mention IP licensing. I don't really see it happening but I would absolutely die of hapiness if it did!

This is fantastic! Cheaper then our plan, too. adding S-ATA would be about 100% brilliant!

There was supposed to be a huge amount of grinning in there, it just got edited out. I never said you argued, but I adore being right ^_^

This is where I do my "I told you so" dance - it's not even really a filesystem, it's just a list of "FILE_ENTRY" structs which are pointers to the files. You quoted from the post I was refering to earlier, by the way

Anyways, I might might might might be getting an FPGA dev board soon. Might. IF I ...

Success! Natively (without any mod chips etc) the cube will complain without the disk drive driver board - however, if you simply remove the laser assembly and leave the driver board in place the cube boots without complaining! Assuming you were then to use SD storage to boot your games it's ...

This uses a YPbPr output rather then RGB, but the concept is the same. Although the actual paper refers to the xbox the YPbPr is a standard sort of connection, so it will work just as well on a wii. Plus, You'll learn a bit about op-amps ...

Is it at ALL possible for a gc to boot without the disk drive? With a comercially availible mod chip bios replacement, for example. If not, is it possible for the gc to boot with only the disk controller but not the actual laser assembly? Thanks in advance!

I don't mean to be cruel, but those pictures are horrible >_<

Soon as your camera is done charging, shoot us up some better ones! We're all dying to settle this once and for all

It should be pretty simple - just have a "loader" DOL that writes your choice to the bootloader section, and then resets the drive. The bootloader section looks to see what image it should load and starts acting as if that DOL is in the disk drive.

This is all getting a little ahead of ourselves ...

marshallh: I agree. I was only thinking along the lines of an MCU because I've been reading about the Propeller Chip from Parallax. It's basically an 8 core, 32 bit RISC chip clockable up to 120MHz (30 effective, 4 stage pipeline) that can detect a rising edge on every clock (120MHz). It's got 32 IO ...
