I never owned a CD-I nor ever played one. Once this emulator comes out and I download it, how would I be able to play the games? Are there ROMs (or BIOS like for the Sega CD emulation) available on the Internet I can find, or do I need to have the actual CD-ROM of the CD-I game I want to play? And basically to play a game, I just have the CD-ROM of the CD-I game in my PC then start the emulator, and open it from there, and it should play?
Also, have you experienced a large percentage of games being incompatible? And lastly, will the CDI emulator you're working on support the North American versions of games, or is it only for European versions as of now?
A really basic question.
Yes, regional coding does not exist on CD-i. There are only some differences in the screen output, sometimes not all the CD-i graphics are visible. The CD-i internally outputs to a fixed format, which then is converted to NTSC or PAL by a PAL/NTSC encoder chip IIRC. I would suspect the emulator would work with this 'internal' resolution, but of course you'd have to ask cdifan that.

There actually is a difference between PAL and NTSC output (the former produces 560 video lines, the latter 480), but nearly all CD-i titles will compensate for this difference. This image is then scaled to your screen window (1:1 scaling is of course fastest and hence default, but you can resize the window).
All the player ROMs I've seen so far will support either PAL or NTSC output, depending on a command-line option. The emulator defaults to PAL.
