That, unfortunately, isn't true and also a whole lot more work then necessary. It would push the emulation boundary out to another new set of undocumented hardware :-(


Well, yes, but that's what we do smile On the scale of a lot of the hardware we deal with here and (especially) on the MAME side CD-i is relatively simple even if we get the slave dumped and emulated. We run the CPU inside the keyboard on the IBM PC/XT/AT drivers (yes, someone dumped the program). We emulate the SCSI chip and bus on the Mac Plus rather than trapping the disk driver out to native code like everyone else. Etc, etc smile

I like this community. smile
Some developers from other emulators are willing to help, not only for the CD-i.

The size difference is hard-coded in the ROMs so this means that it has to be a mini-mmc.


It's definitely not a 220-model player, but it could be useful for figuring out the later-rev chips. About the Mono's amount of NVRAM, I don't mean to sound doubtful, but the BIOS itself only accesses 0x320000 through 0x323fff, with A0 ignored, which is only a total of 8K of NVRAM. Are you certain that the ICDIA site is necessarily accurate?

By the way, I just submitted mouse movement support for the CD-i driver. I gave credit to your nickname in the checkin comment, I hope that's alright.

@Just Desserts

My aunt has a old Highscreen CDI 450/83 console. It is the OEM version of CDI 450.
Not sure you need it and of course my aunt. Anyway, I can ask her next week.

Thank you for offering to ask! No need to ask her for it, though, I would not want to impose. smile

With latest in SVN:

Now I just need to figure out or need help figuring out how it actually polls for discs...

I'll have to check; I wrote from memory. Some models of the 220 definitively have 32KB, but the ICDIA site could be mistaken in which models. The September/October 1996 issue of The Interactive Engineer (also on the ICDIA site) contains an extensive list of player types with description...

Received, slightly reworking slave device handling right now to make the MESS code less ugly than what I currently have checked into SVN. I'll see what I can do. smile

I checked the Interactive Engineer and it is very definite in stating that all 220 versions except F1 has 32KB of NVRAM. 32KB is also found on the 615 and 370.
