Solved SegaCD (MegaCD) - CHD files support

[A Former User]

Hi acris and thanks for your message. Is there an ETA of this release?

Also is there a manual way to do the core update myself manually?

Thanks a lot!

Good Morning,

You can change the emulator and the core directly in EmulationStation:

• Select ANY game within the Sega CD system
• Press SELECT and choose EDIT METADATA
• There you will find on top of the list the option to choose the emulator and core of your choice.

To change all segacd games to genesis plus gx go to the advanced emulator configuration

EDIT:
I forgot to say that you need another (or renamed) BIOS for Sega CD with Genesis Plus GX.
Example for playing US games:
If you have the us_scd2_9306.bin for playing with PicoDrive.....
Make a copy of this file and rename it to bios_CD_U.bin.
Copy this renamed file back to BIOS folder.
Try it with EU and Japan files also (rename to bios_CD_E.bin and bios_CD_J.bin).

If it wont work with EU and Japan, search for these bios files:
Japan= bios_CD_J.bin with md5 278a9397d192149e84e820ac621a8edd
Europe= bios_CD_E.binwith md5 e66fa1dc5820d254611fdcdba0662372

Can anybody help me, my chd roms are not showing up in my rom folder.

[rommel1940]

@deletedaccount how did you make the roms show up in emulation station, I added them to my roms folder and there not showing up, I did everything else listed above. It will play normal bin/cue files fine, but I have a complete chd rom set.

[rommel1940]

@abunille why aren't my chd files showing up in emulation station, there in my sega cd rom folder. Thank for any help.

@rommel1940 You need to edit the es_system.cfg file. 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

chd for segacd will be in the next release

[rommel1940]

@substring how come the previous poster says they got it to work?

[Substring]

@rommel1940 as he explained, just need to edit a file

[rommel1940]

@substring sorry nust seen that, where is that file and how do I acess it. Thanks

[Substring]

@rommel1940 see https://forum.recalbox.com/post/90734

The file is in /recalbox/share_init/system/.emulationstation

You must first mount -o remount, rw /

[rommel1940]

@substring you mean put tne sdcard in my computer?

[Substring]

@rommel1940 if you're asking such questions, I guess you'd better wait for the update

[rommel1940]

@substring I know we're close, I have the sd card in the computer, I got the ledvand light switch to work, I judt can't find what you talking about.please tell me were to acess and edit file, thank you

[Substring]

@rommel1940 you can not edit this file on your PC, but through network. 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
