Identifiying (roughly) what IPL you have.

A guy over on Modretro did a nice little writeup on this and I asked permission to copy it over here. All credit for this writeup to Zeldaxppro.

I am currently in the process of making a GameCube Portable and have been testing many GameCubes to decide what motherboard is the best to use with a Wiikey Fusion Modchip. I recently bought a lot of 5 GameCubes labeled "AS IS" and I was diagnosing the problems (turns out the only problems were faulty disc drives). When I was trying out one of the GameCubes, I noticed that it had a red "Press Start" menu instead of the normal purple Start menu that all the others had. Now I did some research about this in regards to IPL and have not found anything. So I am presenting my theory: If your GameCube "Press Start" Menu is Red, then it is IPL 1.0 and incompatible with the Wiikey Fusion.
Ashen made a statement on GameCube IPL:
All PAL GameCubes = IPL 1.1+
NSTC-U/J GameCubes:
Dol-CPU-10: IPL 1.0
Dol-CPU-11: 50/50 chance of IPL 1.0 or 1.1
Dol-CPU-20/30= IPL 1.1+
Dol-101 (Rev C)= IPL 1.1+
Me and a friend have tested out all the GameCube Motherboards we had and here were the results:
1. Dol-001, NTSC-U, CPU-10, Made in Japan: Red Start Menu
2. Dol-001, NTSC-U, CPU-11, Made in Japan: Red Start Menu
3. Dol-001, NTSC-U, CPU-11, Made in Japan: Red Start Menu
4. Dol-001, NTSC-U, CPU-11, Made in Japan: Purple Start Menu
5. Dol-001, NTSC-U, CPU-11, Made in China: Purple Start Menu
6. Dol-001, NTSC-U, CPU-20, Made in China: Purple Start Menu
7. Dol-001, NTSC-U, CPU-30, Made in China: Purple Start Menu
8. Dol-001, NTSC-U, CPU-30, Made in China: Purple Start Menu
9. Dol-101, NTSC-U, CPU-50, Made in China: Purple Start Menu
10. Dol-101, NTSC-U, CPU-50, Made in China: Purple Start Menu
11. Dol-101, NTSC-U, CPU-50, Made in China: Purple Start Menu
12. Dol-101, NTSC-U, CPU-50, Made in China: Purple Start Menu
Now these results match up to Ashen's statement on GameCube IPL (the information below is based just on our test results):
NSTC-U/J GameCubes:
Dol-CPU-10: IPL 1.0....Had a Red Start Menu
Dol-CPU-11: 50/50 chance of IPL 1.0 or 1.1....Both had Red and Purple Start Menus
Dol-CPU-20/30= IPL 1.1+....Had Purple Start Menus
Dol-101 (Rev C)= IPL 1.1+....Had Purple Start Menus
So this information shows that Red Start Menus indicate IPL 1.0. Now I am not saying this Theory is true, but the evidence above is leaning toward validation. If you guys have anything to add feel free to post it. Thanks for reading.
