Right, can we keep the spam-o-thon down, and actually post constructive material (and you wonder why they have 'official' testers). AFAIK sharing some SPU2 info and register info would be helpfull, but not exactly enough to write a plugin
Next, the BIOS sounds like whale song and distant thunder, yup, thats established

.....anything else.
Less stuff will work with PEOPS SPU than SPU2null as it fakes less, and tries to emulate out the sound, meaning it's far more likely to not have the required code for CDa / the extra complexity of the plugin means it's more likely to hang.
EDIT: Given I banned
DateARockStar - I think the spam should decrease
