We don't support 3rd party images and yours looks like it was customized and changed from the default RetroPie image.
I see you have a number of services (like snapd or bt-device) which are not standard on RaspiOS and I see also an error related to CPU throttling - maybe the system boot is slow because the CPU's frequency is scaled down.
You can use systemd-analyze how long it takes each system service to start, it may help identify which one is responsible for the slowdown.

I just tried to boot with just the lid of the NESPi case removed, where the SATA-to-USB adapter is located, which was of course plugged into one of the Pi's USB 3.0 ports.

Now it boots without problems!

Since these problems started after I performed an update of RetroPie, I suspect an EEPROM update of the Pi made the SATA-to-USB adapter incompatible. I never would have suspected the case lid as it has worked without problems in the past.

At least we finally found the problem. I'll now try to fix this by updating the firmware of the adapter in the case lid and report back whether it worked.

Thanks for your help, mitu! :-)

@mitu ok I can confirm that I am a dumb dumb haha… I actually have an pi3, for some reason I thought I had a pi4 which is why I was selecting the pi4 image. It now worked by selecting the correct image.

Thanks again for the reply. I’m going to leave this here so others can learn from my stupidity haha

@mitu
Thanks for all the help, I finally figured it out. There was a directory config overwriting in the folder with the bios config, when I removed that one my own configs worked and everything is now perfect.

@mitu said in Sega CD Game Not Loading - Annett Futatabi:

What's the actual name of the file you're launching (.cue, .chd) ? I think some characters from it might trigger this error in runcommand.

Annett Futatabi (Japan).chd
Annett Futatabi (Japan).cue

I just renamed the file to "Test.chd" and guess what, it boots! Thanks for the help.

@azurarutlan told you ;)

RetroPie uses the Raspberry Pi OS Lite image - if that will support GPT for the root drive (boot + root), then RetroPie will have no issues with it.

Since the current RPI OS images are using MBR, you'd have to re-partition your disc and copy over the files to the new partitions if you want to use GPT.

@mitu oh ho, I know it's not supported. I tried it as my main configuration for a while and eventually it just would not start any games at all. I'm hoping that because it's on a secondary sd card it'll fix the issues i previously had.

If i had a choice, I would totally prefer to have it on top of raspbian but, whatever.
