View Full Version : Need help saving Sega CD games in Gens 2.12b.

August 27th, 2005, 01:15
Every time I exit out and start up Gens 2.12b then try to play a Sega CD game I get this message:

"Backup RAM cartridge is not initializied. Press reset and go to the control screen to initialize."

The only way to get a Sega CD game to start is to reformat the Interchange RAM and Cartridge memory.

And because of this I will lose my saved games every time. Is there another way to initialize the Backup RAM cartridge without reformatting or some way to turn it off???

Also, how come Save States don't work on Sega CD games? I am able to save in the actual game but I will lose it after reformatting.

This might help -

Option> Sega CD SRAM size>None

Try changing the SRAM around and see what works.

From Gens docs:

The Sega-CD/Mega-CD came with 8kb of internal BRam for save games, this only
allowed fairly basic save game features and is often a problem on real
hardware as games begin to argue over the limited space. External SRam carts
were also available, ranging from 8kb to 64kb in size. The small amount of
internal BRam is less of a problem on Gens because it creates a new virtual
machine, and separate internal BRam file, for each game. However to offer
greater flexibility, and more save slots for each game, Gens also supports
"virtual ram carts". Each BRam file created by Gens stores both the internal
BRam and external SRam data in the same file.
You can set the size of the virtual ram cart to None, 8kb, 16kb, 32kb or
64kb through the options menu. It is recommended that you always set this to
64kb however because if you later wish to increase the size of the virtual
ram cart you will need to reformat it and any existing save data will be

To setup the virtual ram cart for your Sega-CD/Mega-CD game boot the CD or
load your CD image as normal. When the Sega-CD/Mega-CD logo screen appears
press the A, B or C button to access the advanced menu and then select the
memory management features by moving the pointer to "option" or "memory",
depending on the bios version being used. Follow the on screen instructions
to format your virtual ram cart then start your game as normal.

Don't forget that you will need to set up the virtual ram cart function
separately for each Sega-CD/Mega-CD game that you wish to use it with.

Hope it helps :cool:
