After more than 4 years working on it in my spare time, and while it still doesn't work as well as peops spu2 or zerospu2, the plugin has finally come to be acceptable enough for public testing.
I have to note the plugin has many known issues in specific games, like looping, robotized or jumpy audio, but in others it does its job more than fine and in a few it even manages to get better results than its competitors.
For now, you can get binary builds for win32 in here.
