Error loading Mario Kart Double Dash

[monjici]

Anybody had an issue with Mario Kart Double Dash on a PURPLE Gamecube?
The game starts to load, but before the intro video starts, I get the error below. I even get the same error with the bonus disc.

Before you ask:
I tested the game in another GC (Silver), it works fine, the disc do not have scratches.
I tested another copy of MKDD in the purple GC, it works fine. The only difference is that the game that does not work is the canadian version (case only, the game should be the same).

Probably a small scuff/smudge on the disc which the purple unit's laser is having a hard time reading because it's got less life in it.  The laser in the silver unit is likely in better working order.

Hmm...I have the purple gamecube and is the main one I use.  I tested my DD and it worked fine.  Is it Greatest Hits?  Not that it should matter but...
It also may be a rare combination of flaw on the lens/laser and flaw on the disc that just don't work well when used together, hence why they work on other things.

Interesting, maybe I could try swapping the laser parts (if they are fully compatible).

It is the bonus disk version - non greatest hits.
Perhaps I should try having the disks fixed before swapping parts.

I've never heard of that version of the game causing problems, so it may be a later form of the laser with better reading capability. A scratch on a disc will almost never affect a disc drive the same way as another. A silver Gamecube is a later model, if I'm correct. And, after all, the Wii had more than 6 types of drives during its lifespan, so they could have changed out the drive in a later version.

However, I'd try cleaning the disc before swapping the drive.

Believe me, I've cleaned that disc many time with no success
There are no big scratches on it, only miniature ones, but in a very large amount. Not sure if they have been re-surface or not.
I'm thinking about trying the metal polish or toothpaste trick tonight.
