<![CDATA[SegaCD (MegaCD) - CHD files support]]>Hi everyone, I can't find any information on internet about it but I would really like to know how to activate the support for the CHD files in the SegaCD Libretro emulator.

I know the core lr-genesis-plus-gx is compatible with CHD game files as stated on this retropie topic here : https://retropie.org.uk/forum/topic/15751/sega-cd-roms-best-practices/3

I tried adding .chd and .CHD to the es_systems.cfg configuration file but no luck I get a black screen when launching a game and then it goes back to the game list.

CHD files saves up to 50% of the space and is much more convenient as it only have one file instead of a bin and cue sheet files.

Thanks for helping me! 🙂

The very few questions I asked you show that you lack the knowledge to do the edits, despite the hints I gave you. No need to be mean like that. I told you "next update", so be patient, i think you can wait for a month, no ?

what you're being told is not "being more complicated than it needs" it's the simplier and easiest way to do this thing and you would see it if you were willing to learn a little by yourself, but I guess it's more easy for you to worship nazi generals.

/recalbox/share_init/system/.emulationstation/es_system.cfg

I access it by plugging my SD card in the computer. I'm on a mac and I use Paragon extFS to access the content because it's a linux ext3 partition.

On Windows I think you can access it with a software called Partition Guru. Haven't tried myself.

Hope this helps.

I got retropie figured out just fine, I wonder why that's more successful. Maybe its asses like you and the moderator who think something that's more complicated than it needs to be is easy for a first time user.

Or read the manual, the wiki, watch tutorials and make at least a little effort to learn (easy) things by yourself, this the recalbox support forum, not a computer handling 101 mooc

Check for winscp + recalbox SSH access, there are plenty of tutorials. And I still believe you're making a mistake trying to do this on your own as you have no idea of what you are doing

Find the emulator segacd and where you see the line with supported file types just add .chd and .CHD

Like that the system will check for this type of file and find the chd iso. If you've added the correct bios with the correct md5 and correct name they will launch and play just perfectly.

Have fun 🙂
