SegaCD missing BIOS (linked)

Post by rooted »

Why is only SegaCD missing the necessary BIOS (s)?

I couldn't understand why I couldn't get any files to run, also ISO should be added to the configuration by default since a lot of ROMs come in this format.

To fix you need to unzip the linked files to:

Code: Select all

/opt/libretro/genesis-plus-gx/
The best formats to use are (*.cue + *.img) or (*.chd).

If you use ISO it will work but you need to add the extension to the emulationstation configuration.

Location:

Code: Select all

/etc/emulationstation/es_systems.cfg
Add .iso after .cue in the configuration:

Code: Select all

        <system>
                <name>segacd</name>
                <fullname>Sega CD</fullname>
                <path>/roms/segacd/</path>
                <extension>.cue .iso</extension>
                <command>retrorun -a 1.333 -s ~ -d /opt/libretro/genesis-plus-gx /opt/libretro/genesis-plus-gx/genesis_plus_gx_libretro.so %ROM%</command>
                <platform>segacd</platform>
                <theme>segacd</theme>
        </system>
Keep in mind that ISO with mp3 music files will work but the mp3 music will not play, so it's best to stick with the two formats I listed above for full compatibility.

Can you please make an external link?
I think the BIOS contents should be still owned by Sega.

Sure, no problem. So they were intentionally not included, I understand why.

I would think no BIOSes would be included?

While I'm not sure I think the other systems don't require BIOS any longer.

I posted the Release Notes that indicate which emulators require BIOS files and where they go:
