A lot of old MS-DOS games use the AdLib as the best sound card it supports. And guess what, Virtualbox doesn't support the AdLib!!! Please add support for this as I really want to play DOS games with those lovely 8-bit noises.

Oracle's Virtualbox development is driven mostly by their customers' needs, and it is unfortunately unlikely that their customers want to play DOS games on their expensive Virtualbox licenses.

The likelihood of this hardware getting virtualized is very low. Code can be submitted if you want to virtualize it, or maybe another program, like DOSbox, might get your games going.
