Crash Tag Team Racing for the GC also gives the same warning message, it crashes
after selecting OK a few times, I haven't tested Nitro Kart and Wrath of Cortex.

Confirmed that this game makes extensive use of the Data Block Cache instructions (I
tested Crash Tag Team Racing for GC). Unfortunately, I'm not sure if we can feasibly
implement them...I was told that it will result in ridiculous amounts of slowdown.

The Incredible Hulk: Ultimate Destruction also has this error :(

dcbt and dcbtst are both simply prefetch instructions : they should not be emulated.
Dolphin shouldn't give errors upon their execution.

So I suppose this is why CTTR always slows down to some degree. Isn't there some way
to emulate these instructions without the slowdowns? Because apparently there are
several game that use these instructions and they'll be otherwise left out of
Dolphin's playable game library.

well there is a way but you would need to convert the game to a windows application
and as far as i know there isnt anything that does that

CTTR works now, and at a great speed too.
