CD-I emulation through lr-mess

[escc1986]

To Get CD-I Working on Retropie on a pi 4

Step 1 :
Goto :

RetroPie

RetroPie-Setup

manage packages

manage experimental packages

lr-mess

install the binary

Step 2 :

Rename your RetroPie-setup directory (/home/pi/RetroPie-Setup)

Go into Putty

copy paste this : git clone https://github.com/valerino/RetroPie-Setup.git

( Note: git clone https://github.com/valerino/RetroPie-Setup.git needs to be in the /home/pi )

should look like this in putty

(git clone https://github.com/valerino/RetroPie-Setup.git

Step 3 :
Goto :

emulationstation

RetroPie

RetroPie-Setup

manage packages

manage experimental packages

lr-mess-cdi

install the source ( is a fast install )

put roms in rom folder titled cdimono1

Step 4 :
You will have to find the BIOS roms.
lr-mess will look for this BIOS file : cdimono1.zip

Normally it would contain :
cdi200.rom
cdi220b.rom
cdi220.rom

But with the "new lr-mess" it has to contain :
cdi200.rom
cdi220b.rom
cdi220.rom
zx405037p__cdi_servo_2.1__b43t__llek9215.mc68hc705c8a_withtestrom.7201
zx405042p__cdi_slave_2.0__b43t__zzmk9213.mc68hc705c8a_withtestrom.7206

The last 2 files can be taken from the cdi910 file. (think it's also a zip)

So if you have both files (cdimono1.zip and cdi910.zip). Unzip those 2 and create a new zip file called cdimono1.zip that contain the 5 files described above.

You have to put that cdimono1.zip in /home/pi/RetroPie/BIOS
