CD-I emulation on Raspberry Pi 4: what am I doing wrong?

(remember that Linux is case sensitive so something like .Chd would not work).

Case sensitivity has nothing to do with Linux and has everything to do with the file system you happen to be using with it. ext4 = case sensitive, exfat = case insensitive, etc...

Here is the pastebin from /etc/emulationstation

Here is the pastebin from /etc/emulationstation/themes/nbba/extras/emulationstation

https://pastebin.com/L26Q45K8

You'll noticed the path in the second pastebin was changed to ~/RetroPie/roms/cdimono1 opposed to /home/pi/RetroPie/roms/cdimono1 like the first pastebin. Originally, I had both written as /home/pi/RetroPie/roms/cdimono1 and when I noticed all other entries were ~/RetroPie/roms/ I changed it thinking that was the cause of the problem. Not the case.

Also, file names are exactly as I wrote them in the first post. All files are .chd, not Chd or CHD, etc.

The file looks ok. The 2nd file doesn't matter, it's not used by EmulationStation (looks like an example for es_systems.cfg).

Check if you don't have a custom es_systems.cfg in $HOME/.emulationstation, that will have priority over the configuration file in /etc/emulationstation.

~/RetroPie/roms/cdimono1 and /home/pi/RetroPie/roms/cdimono1 are pointing to the exact same place. The ~ means "current user's home directory" which is /home/pi/.

No es_systems.cfg in $HOME/.emulationstation

@zerojay

I kind of figured, but you never know sometimes. I'm still fairly new to linux based systems.

mitu

Try running emulationstation with the --debug parameter and see if you sport any errors/messages about cdimono1. At the very least it should say it doesn't recognize the cdimono1 platform. The messages are aslo logged to $HOME/.emulationstation/es_log.txt.

Looked through the log and found this:

Sep 12 10:04:02 lvl1: Unknown platform for system "cdimono1" (platform "cdimono1" from list "cdimono1")
Sep 12 10:04:02 lvl1: Error - folder with path "/home/pi/RetroPie/roms/cdimono1" is not a directory!

So I went back and checked the directory and the roms folder was misspelled (cdimon1 instead of cdimono1). Knew it had to be something stupid...

Anyway, the system shows now so thank you for your help!

Now to figure out why it's freezing upon loading the game. I'm getting a screen with very small text in the middle of the screen that I think says "Initializing"? It locks the system and I have to reboot. BIOS problem maybe?

The guide never said what BIOS file you need exactly. Only to put "it" in the main roms folder (which is weird, shouldn't it go in /home/pi/RetroPie/BIOS or the cdimono1 folder?). Anyway, the BIOS files I have are cdibios.zip, cdimono1.zip, and cdimono2.zip. Any ideas?

mitu

I think it may be the same issue as reported here - either the BIOS is not correct (was updated recently) or MAME actually disabled the system (marked as NOT_WORKING).

You can check /dev/shm/runcommand.log for any errors, but I think they'll be similar to the ones reported in the topic I linked.

@mitu

Thanks so much! I'll give that topic a read and see what I come up with.

swagford

Yep, same error. If I'm understanding that thread correctly, the only way around it is to have an older version of MAME? Which you cannot obtain unless you had a backup of it?
