DogP released the “Virtual Boy Sound Generator”, a program that pretty accurately emulates the Virtual Boy’s sound processor and so let’s you test VB sound code on your computer instead of always having to load your flash cart and test on hardware.

Release notes:

DogP released version 1.1 of his VB Sound Generator. It has a few minor changes in how values are processed, as well as a few other small changes. The source code is now also included.
