Adding CDROM emulation support? #50

I know this is probably a long shot but I was wondering if you could get in touch with Kevin Moonlight and ask him if he can share his Panasonic CDROM emulation code for use with the PicoGUS?

He made a video about what he's done here -

At present we don't really have a way of getting CDROM audio working in DOS on real hardware without a real CDROM drive, so working CDROM emulation would be nice to have.

Hi, I’m in regular contact with Kevin. Being able to use his CD-ROM emulation is a definite possibility for the PicoGUS. Stay tuned!

Will do!

... can... you have that done by Thursday last week? {smirk} I've been LOOKING at another solution, but, if there's enough room on this PGUS.... Wow.

The big hurdle is getting USB mass storage fast enough. As is with the TinyUSB library, it's not fast enough to emulate a 1x CDROM drive. AFAIK it's a software issue, not a hardware one.
