Gamecube Service Disc

For those who don't know it, check it out here.

The big problem with it is that it's made to work only on old Gamecubes (probably Rev. A only), newer ones detect the disc fine but can't boot it (stays forever in the black screen, no messages or warnings). (More discussion here.)

My question is: it's possible to patch it to work in all or at least most Gamecubes...?

I imagine it would be easy.

The GC probably just detects the title ID of the disc.
If you open it in GC-tool or maybe even a hex editor, you could change the ID and have it boot.

However, that would assume that you have a modchip and you burn all your games.
With the introduction of swiss, hardly anybody uses discs.
I imagine the GC would boot the image no problem via swiss.

As a side note, I wonder if the freeloader would allow the disc to boot.
Does anybody know exactly what the freeloader does?

Well, I tried editing the disc ID and even replacing the bootloader with one from other game, and still Swiss always shows the exception screen while 'checking game' after I try to launch the game.

SD-Boot stays in the black screen after I try to.boot it.
Runs fine in Dolphin though.

I think they use some other hardware trick..

It boots on my GameCube. Burned it to a mini-dvd. Shows up with correct icon and banner in menu as well. Don't have the newer DOL-101 cubes though. Perhaps it's those it has trouble booting on.

You should be able to just use the top entry and boot that? Can you post a picture?

I went to take pictures just now and I chose the top entry as in "boot the disc". then it startes patching 412 files. once thats done it shows me a huge list of .dol files. now I noticed the "or press b to boot normally" that I didn't see before!
so there is no problem, I think.
I choose to boot from disc because from SD it errors with "failed to find function for patching" on almost every DOL making it take an eternity to finish.

That's kind of crap, I should add a warning for this scenario and allow it to just be booted directly without patching by default.

Anything new on this situation? It still patches 412 files when loading from an SD Gecko before letting me choose which dol i want to boot from.
