Yesterday was my first time successfully ripping games using my wii and cleanrip. I started with Gauntlet Dark Legacy, and I haven't had a problem with that game yet. But when I tried "Metal arms: Glitch in the system", "Legend of Zelda: Wind waker", and "Super Mario sunshine", they've all opened a black screen with no audio or information on the window border.

Opening metal arms gives me the error "IntCPU: Unknown instruction 148a04f1 at PC 8020599c last_PC = 812fffc8 LR = 803405d4".

Wind waker gives me the error "IntCPU: Unknown instruction eb73f949 at PC 80205d6c last_PC = 812fffc8 LR = 80309ab8".

Opening Super mario sunshine gives me no error at all.

CPU: AMD FX-8350 4 GHz 8-Core Processor
Video card: STRIX-GTX750TI-OC-2GD5
RAM: G.Skill 2 x 8 GB

Wind Waker log
Super Mario Sunshine log

I would really love to relive some of my childhood through these games, but I'm not experienced with Emulation at all, and I feel completely clueless at the moment.  Huh  Huh  Huh
Have you verified your dumps (MD5)?

Considering I'm not entirely sure what that means, I'm gonna guess not. How do I go about doing that?

I got this message for all three games.

"No problems were found.


 Because GameCube disc images contain little verification data, there may be problems that Dolphin is unable to detect."

But what were the MD5 hashes for each of them?
SMS: 899e6457a3af3f5bb1fbe340382db3d6
Wind waker: 69c1c56a92d10667e6560608a6859193
Matal arms: 69c1c56a92d10667e6560608a6859193

What is the MD5 supposed to tell me?
The MD5 hash can be thought of as a mathematical "fingerprint" of a file. Changing 1 byte in the file should change the MD5 hash. The idea is that you take the hash from your games and compare them to a hash from a database like Redump.org. The hashes on Redump are from files that are 100% clean dumps, byte-for-byte copies of the data from the original disk. If your hash does not match theirs, then something is wrong with your dump.

For example, Super Mario Sunshine has the following MD5 hashes:

PAL -> 72c4860d8555d5e790628e348abc244d
NTSC-J-> 3b07a4bb22db926b177e207f9d7f0d87
NTSC-J (Rev 1) -> d23c79fcb8f7cb978f4363e9393a92ea
NTSC-U -> 0c6d2edae9fdf40dfc410ff1623e4119
KOR -> 1f8d7bc062ab3c532a76811fbcceb229

So, your file matches exactly none of the verified, good dumps. You have a bad file. Redump your game from the original disc, verify it matches the hash for your region, and you should be good.

That cleared things up a bit, thanks. 
My MD5 on all three games doesn't match redump when I use dolphin to verify, but the MD5s cleanrip provided in the .txt file match. so I'm not sure if it is the rips or something else. Assuming it is a bad rip, will a second attempt even yield different results? I've only successfully ripped 1 out of 4 games.

If the MD5 hashes in CleanRip's txt file match Redump, then something must've gone wrong after the actual dumping. Did CleanRip output multiple ISO part files for each game, or just one ISO file for each game?
