Genesis Plus GX Sega CD Support Coming Very Soon.

Some tricks to prolong battery life:

With the Sega Saturn, just back-up your current saves on your 4in1 PAR or memory cart. Then remove the battery. If you keep your system plugged in all the time, it doesn't die as fast.

With the VMU, just don't leave them plugged into the controllers all the time. When the console is off and the VMU is plugged into the controller, the batteries always die withing a month.

Everything else you just replace the batteries of course since there is no way around it. Keeping your consoles plugged in all the time does help the battery life.

But as others have mentioned the internal memory is more than enough and a battery replacement isn't too painful if needed. I play the SEGA CD on original hardware all the time and have never had the need for a RAM cart.

Not if you want to play Lunar II or Shining Force CD or really any RPG on the system. They will eat up almost all your internal memory in just one save.

Besides, I'm really not in the market for replacing the internal battery or buying a backup RAM cart, regardless of it's price. The thought of having to deal with dieing batteries and 15 year old optical disk drives are not very appealing to me. I honestly would much rather emulate it on my Wii with 240p component out put on my 2009 SDTV.   

In fact the only reason I own a real Sega CD is because I found it in a public dumpster next to my brother apartment along with a copy of Lunar II (no joke!).
