[Tutorial] CD-I Emulation in RetroPie via lr-mess (warning: slowdown, especially during FMV, but surprisingly playable)

I used the function to update everything, but nothing has changed
do I have to use any particular function?

No, as I said, you need the new image based on Raspbian Stretch, updating from RetroPie-Setup will not get you the new OS. Or, if you feel adventurous, you could use apt-get to upgrade from Jessie to Stretch - https://retropie.org.uk/forum/topic/16145/retropie-upgrading-raspbian-jessie-to-stretch. Note that the recommended way is to install the image from scratch

For RPI users it is recommended to start from a fresh image with this update. It is possible to upgrade the system from Jessie to Stretch but there have been reports of issues by some people when doing so.

@victimrlsh There are some good games on CD-i. Lords of the Rising Sun was one of my favorites. The Space Ace port was probably the best I've seen, other than the new PC ones. Ceasar's World of Boxing was also pretty good. Burn Cycle is another one that saw a lot of play time. And I still remember my whole family playing The 7th Guest together. Those were good times.
I remember Chaos Control, Escape From Cyber City, and Mad Dog McCree being pretty fun. Although Escape from Cyber City was impossibly hard. The zelda games aren't the best, but they're not complete garbage either. They did something different, and I enjoyed them well enough as a kid. If you go in with a super negative opinion, the game may even surprise you.

@liquiddivide My favorite laser disc game was Cliff Hanger, which was pieced together from the Lupin III movie The Castle of Cagliostro. I highly recommend both the movie and the game.

@victimrlsh I'll have to give that one a try. Never heard of it.

@liquiddivide Just make sure your suspension of disbelief is high enough to surpass the laws of physics...

@db666 what you posted for windows is same result as posted in the guide and works under ES and emulators.cfg
:-)

Figured I should necro-bump this thread with a bit of an update: since the Pi 4 is now officially supported by RetroPie as of 4.6 (even if it's only considered in a beta phase), I decided to test lr-mess with CD-i and I can confirm it now runs full-speed, at least with Hotel Mario. :)

I should note that I did overclock to 1.75ghz, but I don't think that is necessary to achieve fullspeed CD-i emulation in lr-mess (though I've yet to test without an overclock).

Another way to run CD-i (cdimono1) with MAME standalone (like MESS without Lr)

go in /opt/retropie/configs/cdimono1
open your emulators.cfg

add:

mame-CD-i= "/opt/retropie/emulators/mame/mame -c -autoframeskip cdimono1 -cdrm %ROM%"

To set your "Input (general)" and "Input(this Machine), follow step 10 and 11 of this Tutorial.

You can use .chd without specific MAME naming and without dummy file.
