Here are my results with 1.126 (if you want USB Gecko logs, I can grab them):
Zelda: Collector's Edition: Zelda 2 (NES) boots now, but Zelda 1 still does not.
Zelda: OoT/Master Quest bundle disk: The menu now boots (required audio streaming (or the ability to disable it) iirc), but it only allows Master Quest to be booted, regardless of which game you choose. It has static and noise in the audio, like OoT does in Zelda: CE.
Ikaruga: Goes in-game now instead of crashing, but without music (duh).
Pokémon Colosseum: Same as it's been for a while, can't save, but seems to work fine otherwise.
PSO Episode 1 & 2: Still turns the Wii off.
PSO Episode 3: Still crashes on a black screen.
(I realise both PSO games need more than a simple fix, I'm just stating them for the complete list)
Nintendo Gamecube Preview Disk May 2003: No menu background music (needs streaming audio). Sonic DX demo hangs with a black screen (no useful output). Viewtiful Joe demo crashes with a black screen (

That's all I feel like testing, for now.
