Thanks for updating the thread, PiXi. Sorry to hear that the Wasabi Zero does not work as hoped.Had received the Wasabi Zero yesterday and unfortunately it was wasted money. WiiPower was right as usual!
- GameCube games with audio streaming plays garbled audio and playback of a correct sound only possible after pressing reset button
- Issues with some games (Eternal Darkness NTSC has endless repeated audio in very beginning (can be skipped); MGS Special Disk NTSC-J just gives black screen when you press something in menu)
- It's impossible to run import games without MultiGame ISO Creator (I guess it's because of 4.3)
- No 480p or 576i support, only 480i is available, all other modes just shows green or black screen (and again maybe because of 4.3)
...and of course NeoGamma doesn't works with installed modchip
Although I do not know for sure, I have an idea that proper audio streaming support requires the "secret" serial port which is used by YAOSM and the original Wiikey. The two chips that I tried (Wiizard, Wiikey 2) which used alternative connection points (like Wasabi Zero) had problems with audio streaming like you describe above. With a bit of work, it is possible to restore the missing connections and install YAOSM 3.2 in your Wii, but it would require some fairly meticulous work to access the cut pins on the drive controller IC.
This picture shows an original Wiikey installed on D2B with cut pins:
From what I understand, you can install Priiloader to restore region-free support for 4.3. That would be easier and safer than downgrading.1) Downgrade from 4.3 to 4.1, looks like it's possible using DOP Mii -, it must help to restore RegionFree and maybe unlock 480p and 576i modesCode:http://www.youtube.com/watch?v=-o2EqynOcZw
2) Remove softmod after downgrade, maybe some bugs was induced by software modifications
...but if these two steps are just my pure fantasy then I must admit modchips are worse than even emulators and much worse than softmod and only chance to get fully working audio streaming is to get GameCube console!
The problem with using a modchip with Neogamma is that Neogamma mistakenly thinks that the backup disc is a retail disc. Normally Neogamma will allow playback of streamed audio on retail discs and mute streamed audio on backups. However, if the modchip messes up audio streaming, there's nothing Neogamma can do to fix it. A properly working modchip is necessary.
Another alternative is to find a DMS/D2A/D2B drive board (without cut pins) and install YAOSM 3.2 on it. That's what I did, as I could not find a working audio streaming solution with my original D2C2 board. As mentioned previously, I can confirm that YAOSM 3.2 plays all audio streaming games perfectly, just like a modded Gamecube.
