#PicoGUS is now an ODE! I've just released firmware v3.0.0, which adds Panasonic CD-ROM drive emulation. Put some ISOs or BIN/CUE files on a USB stick, plug it into your PicoGUS, and you've got a virtual CD-ROM drive that works in DOS and Windows 9x and supports CD audio. [edit: fw v3.0.1 fixes MPU-401 output in modes w/ CDROM] https://github.com/polpo/picogus/releases/tag/v3.0.1
Maintaining my perfect record of needing a bugfix release immediately after a big feature release, PicoGUS firmware v3.0.1 fixes MPU-401 output in SB and USB modes. https://github.com/polpo/picogus/releases/tag/v3.0.1
