I'm trying again to make it work and to my surprise I found these responses on my former comment. I'm not being successful in it in making it work but I've realized I need an emulator and such. I've successfully been able to run some Cd-i on MESSUI, but so far I haven't been able to make this copy work. I've tried to convert it to .cdh, as suggested by the few tutorial on internet and still no luck.
@Mitchell Beazly thanks for that tip, it does open it with IsoBuster. Nothing wrong with the Cd-i copy : )

UPDATE: so... I've kept on trying, now with the Cd-Emulator v0.5.3 beta 4 (patched to delete the limitation), and....it works...but...horribly, to the point it cannot be much "played" : / .

This disc image is made for an old entertainment system called CD-i. It was used to play movies, music, and videogames and to connect to the internet, It could also manage E-mails and even download things from it from the internet. But it could only use discs that were made for it specifically.
