This is very interesting, considering that there is not a good emulator for the CD-I.
Thanks for his work.

I'm not really sure how much farther I'll be able to go at this point, though. I'm pretty sure it now wants some sort of communication with the CDIC and SLAVE devices, both of which are completely undocumented, as far as I've been able to find. In case anyone is interested, here's a list of the offsets that it currently hits on the SLAVE device, and the values which it writes:

Interestingly, if I pull a CDIC interrupt (line 2), the BIOS briefly tries to chat with the SLAVE device, but not much more than that.

But kudos to Arbee and JD for the hard work so far. There might not be good emulators for platforms other than Windows, though. (although I'm betting WINE can handle it.) - Stiletto

The Cd-i emulator it's just horrible...
That freeze after a small time in free version...
And is so strage to play that in mouse too...
But i'm very excited with the works in MESS cd-i driver!
You work is very very welcome, JD!

Oho, now that's interesting That's cool, where'd you find that? If, upon initial boot-up, the UART returns 0x01 and then any other ASCII value, it decides you want to be in test mode and allows you to select any of those tests. They're all completely worthless, however. The CDIC test expects RAM to be at a certain range and then tests one single register. The SLAVE tests the SLAVE version register. The X-Bus test expects one 32-bit word to be returned from the SLAVE device. It's all just totally useless.
