----------------------------------------------------------
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.
[+ Gens actually calculates the track order by looking at the numbers at the
end of the .mp3 files. You can use any numbers you want, for example 10,
27, 32... however it's easier to rename them in the way shown above.]
Once you've set up your CD image and .mp3 files as shown you're ready to
begin.
Instead of clicking on Boot CD in the File menu click on Open Rom as if you
were going to load a normal Genesis/Mega-Drive game. The Open file window
will appear as usual, click on the arrow on the "Files of type" box and
select "Sega CD isos files (*.iso,*.bin,*.raw)" from the drop down list. Now
locate your CD image file and click on the Open button to begin loading the
game. Gens will now initialize Sega-CD/Mega-CD emulation and begin reading
the CD image/.mp3 files. Please note it can take a while before the Sega-CD
/Mega-CD bios screen appears as Gens needs to calculate the length of all
the files before it can begin.
