adding RAM to a Sega CD?

[Edmond Dantes]

So I've owned 3 model two Sega CDs in my life. Two of them had no built-in RAM (the one that did, broke, and I sold it for parts).

So I wonder is there a way to mod Sega CDs so they have RAM again? I know I could just get the ram cart, but the problem is no game saves directly to that so you always have to remember to reset the system, open the CD hatch and transfer the data from the phantom memory over to the cart. Since I'm so used to just turning the system off and leaving it sometimes is a little much to remember.

So, any advice for me?

Wasn't it more of the battery dying inside the system? I could have sworn I heard about people replacing it.

Someone chime in, as I'm no help here <_<

Since it can store the save through a reset it's a dead battery - I've heard of it, but luckily, I have never had to change one.

I literally just did the replacement in this thread last night since I finally had time. One thing to note though, is that over a couple years the battery will degrade and run out of power unless you put an equivalent CR2016 rechargeable in there. Also, if you don't turn on the system for several years the battery will probably just run out and you'll need to replace it anyway.

Alternatively, if you only care about your saves for the short term (by this I mean a couple years), slap a CR2016/CR2025/CR2032 in there. The only difference in them is the outputted amperage, so they'll still work but will run out of power faster in relation to the battery number increase.

Should be careful about putting a non-rechargeable in the system. There is still voltage that is used to charge the location where the battery is. Might not be enough to do alot of damage but it is usually not a great idea to put normal batteries in a charging state. Some arcade boards have rechargeable batteries and when people swap them out they remove or disable the charging circuit to use a normal battery.

Except that the battery inside the SegaCD isn't rechargeable.

Must have been thinking of Dreamcast.

It definitely is, type ML2016. The manual even addresses the issue:


The Sega CD will retain saved games for up to one month without being powered on. After that time, saved data may disappear [...] After reformatting, leave the Sega CD powered on for at least six hours before using its internal memory again

Same as above..Its rechargeable for sure...

Funny given the CR2032 I popped into mine has never exploded.
