Hey all, I have the game running on a PS2 via OPL for testing; however, the PS2 Rockband Mic is recognized, but I don't see any change in audio levels, nor do commands come through.

I noticed that the Snowball Mic also is recognized as a USB Mic, but the same issue applies. Are there any troubleshooting tips when running on official hardware via something like Open PS2 Loader?
