Before you can begin playing Sega-CD/Mega-CD games you must configure Gens
ready for CD emulation:
1. Download the Sega-CD/Mega-CD bios files which are available from
Eidolons Inn (http://www.eidolons-inn.de).
2. Set the location of your bios files through the Directories and Path
Configuration in the options Menu.
3. Whilst the Directories and path configuration window is still open you
also need to set the default BRam directory for Sega-CD/Mega-CD save
games. Click on OK to save your settings.
4. Open the Option menu and click on the Current CD Drive option, this will
bring up a list of available CD and DVD drives, select one of the drives
from the list. If no drives are shown then you do not have the ASPI layer
installed. You will need to download and install the latest ASPI drivers
before you can play any Sega-CD/Mega-CD games.
Gens is now ready for Sega-CD/Mega-CD emulation.
