| | | * Running a Sega-CD/Mega-CD Game from a CD image/Mp3 file:
-------------------
--------------------
-------------------
Gens also supports CD images (backups) in .iso/.bin/.raw format with .mp3
audio. It is recommended that when using CD images that you have both the CD
image and the correct .mp3 files available as many games will not run if the
audio tracks aren't present.
For Gens to correctly identify any .mp3 audio tracks for your CD images they
have to be placed in the same directory as the CD image file with the same
file name as the CD image followed by a track number. For example if you are
using a CD image called Blaster.iso with three .mp3 files you would need to
put all the files in the same directory and rename them like this:
Blaster.iso
Blaster 02.mp3
Blaster 03.mp3
Blaster 04.mp3
There are a couple of important points to remember when setting up your CD
images & .mp3 files for use with Gens:
* The CD Image should NOT be numbered, it won't work if you have
"Blaster 01.iso" instead of "Blaster.iso"!
* The CD image acts as track one so the first audio track will always
be track two+.
* The track numbers must also be a TWO DIGIT number: 02, 03,...10 etc.,
NOT 2, 3,...10.
* The space between the file name and the track number is optional.
