CHD games not working for Sega CD.
The games as .cue files are working fine. I convert them using CHDMAN from the download link provided on the wiki of this website and they seem to convert fine but when I try to run the .chd file I get the standard white box saying what emulator is launching but then it just closes and shows the list of games again without the game loading. I'm using the lr-genesis-plus-gx emulator.
@Krytern Seems like a missing BIOS - do the games work as
.cue/.binor you get the same problem ?
Please addd more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
@mitu The games work fine as .cue files so the BIOS seems to be working for cue files at least.
Sorry about missing the details of my system, here they are:
Raspberry Pi 3 Model B+
The official white power supply, 5.1V 2.5A
Retropie version 4.4 built from Pre made SD Image
No USB devices connected
Using a Dualshock 4 controller via bluetooth
@Krytern Can you get a log file from the emulator to see if we spot any errors ? When launching the game, open the Runcommand launch menu and enable 'Run with verbose logging'. After the game exits back to Emulationstation, get the
/dev/shm/runcommand.logfile and post it on pastebin.com.
@Krytern The error I see is
[...] [libretro INFO] INFORMATION - Loading 0 bytes ... [ERROR] Failed to load content.
which means RetroArch cannot read the file or the
.chdfile is empty ?
How large is the
@mitu It is 317MB
@Krytern I wonder if it's because of the older version of RetroArch - is there a reason you haven't updated it ?
@mitu I didn't realise I was using an old version. I've just updated retropie-setup script and the stuff in there, including RetroArch but I am having the same problem. Here is the new log: https://pastebin.com/7x42EY9A
@Krytern The new log is not very different than the old one. Is there a way to check if the CHD is valid - maybe load RetroArch on your PC ?
I'll check one of my CHD on the Pi system I have, to see if there's some emulator related error, but I doubt it, there haven't been any major changes at all in the Libretro core in the last months.
@mitu Looks like it is a problem with the CHD file. I used CHDMAN from the wiki on this site and it didn't give any errors so it is strange I am having issues.
@Krytern Did you test it on the PC ? You can run
chdman -i info <chdfile>to see what CHD version is used.
