EMULATING SONIC CD BETA

At the moment the only emulator that will run the game is Ages. Here are the steps to setup Ages to work with Sonic CD beta.

STEP 1: Load the Sega/Mega CD bios files.

You can download the Sega/Mega CD BIOS files from Eidolon's Inn.
http://www.eidolons-inn.de/sega/segacd_dev.html

 Go to Config -> FILE IO -> Load System ROM -> SEGA CD (U)
Load the USA Sega CD bios file. Make sure it is the right USA bios version
(Eidolon's Inn will tell you)

Go to Config -> FILE IO -> Load System ROM -> SEGA CD (E)
Load the European Sega CD bios file

Go to Config -> FILE IO -> Load System ROM -> SEGA CD (J)
Load the Japanese Sega CD bios file

STEP 2: Set the region

Because AGES doesn't run the Japanese Bios correctly, you need to set the region to USA not AUTO

Go to Config -> Machine -> Miscellaneous -> Region -> USA

STEP 3: Disable Z80

Go to Config -> Machine -> Genesis -> Disable Z80 and make sure it is ticked.

STEP 4: Set default CD drive (if you plan to use the boot CD function)

Go to Config -> FILE IO -> Set Default CD drive

Choose your CD Rom drive.

You are now ready to run the game!
