Wind Waker, test dungeon help

[RupeeClock]

I've been playing through Wind Waker on Dolphin, and it's been playing near perfectly, rarely freezing on me, great. European version mind you.
So I decided I wanted to check out those fabled debug rooms, and Dolphin like many games has a pre-compiled cheats list.

There's just one thing though, when I try to activate any of the test rooms, all I get is a compile error followed by a crash.


(I know Dolphin's cheat support isn't perfect)

There are also some patch codes, two called hidden dungeon, and snow test room, but I'm not really sure what these do.

So, anyone ever successfully played the test areas on Dolphin? Thanks.
