Hi.
Just of curiosity... Is there some kind of battery backup in the Duo-RX to save games or how does it work?
TIA.
-
Yeah, all Duos have save game memory. So do TurboGrafx-CD consoles.
Only certain games support it, and certainly they will let you know if they do.
-
Thanks. There will be no battery swapping then? Nice to know :)
-
I understand it's a "rechargeable" battery that replenishes every time you plug in and turn on your Turbo.
Some game manuals say you need to turn on your system every two weeks to ensure the memory stays intact but I've left my system unplugged and off for months without trouble.
-
Sounds like nothing to worry about then. I salute you :-"
-
yes, those batteries are now over 10y old. when you switch on the DUO the batteries always getting charged a little bit, and the save data keep staying on it. but if you don't turn on your DUO periodically, let's say over more than 3 month or so, all the data could be gone for ever. that's just my experience i had over the last years with my DUOs.
-
In that case, i guess i can replace the battery? I presume that the machines in stores and Ebay (Dream Stars, Hit-Japan etc) might have a problem with the battery since they are on sale for some time. My next question is this: Is it soldered?
-
The batteries usually are not soldered. They are in a round plastic holder and can easily be popped out and replaced. I had to replace the battery in my saturn once. I think that either way, new or used battery, you may still have to turn on the system every now and then.
-
The battery is easily removed on the Saturn. I remember that from the time i used to own a white system. But i don't have to worry about the battery on the PCE. I can almost figure its as easy removing as the Sega?
-
It's not a battery, it's a capacitor that keeps the sram chip powered.
-
I was just about to say exactly what Seldane did. But I won't since he already said it. I have no idea why I'm even posting. Oh well, 'tis my lot in life.
-
yes. kind of double layer capacitor. something like this:

-
Don't forget - like all caps, they can die of old age and need replacing.
-
Now i just hope this capacitator can be purchased in any electronics store. It would be a shame if the opposite was the issue here :(
-
Capacitors are usually pretty easy to find.
But unless you're experiencing problems with yours, why bother?
-
Exactly. I just want be to safe for the future i guess.
-
For what it's worth, I can't think of a single person who's had any trouble with their save game memory on an NEC system, off the top of my head. I certainly never have.
If you're really worried about it, what I would do is just get a Tennokoe Bank memory card and backup your system's memory every couple days and just forget about it. I really wouldn't be concerned until your system actually stops retaining it's memory. It's probably more trouble than it's worth to try and fix something that isn't broken yet, and may never be as long as you own the console.
-
I can see your point here. The Tennokoe Bank is certainly an option i have considered. Well, im not paranoid. As i wrote earlier, i just want to be safe for the future. Im really surprised to hear that no one (that you've heard of) has experienced problems with the memory function. I mean..The system has a few years on the back now, so logically the problem should have occured by now.
Forgive my bad engrish :roll:
-
I actually know of several people whose SRAM isn't working due to a bad capacitor. It's a common problem. In Duo machines, anyway.
-
You'll need a Tennokoe Savings & Loan card if you ever plan on playing Space Fantasy Zone, as that unreleased game deletes your entire file cabinet without asking.

Hi Leg Fantasy did the same thing to me. I was almost finished Cosmic Fantasy 3 too. :(
-
We should compile a list of games that rudely auto-delete everything in the File Cabinet. Space Fantasy Zone doesn't care if it's full or not. Even if there is only one other small thing saved, it goes bye-bye. I know there is at least one other game besides Hi-Leg that does it, because it happened to me once before on a game I downloaded from the internet before Space Fantasy Zone.

Holy crap! Thanks for telling me this as I was completely unaware! Luckily I've only played Space Fantasy Zone via emulation, but have been meaning to burn it and play on real systems some day. Yes, yes; we definitely need to make a list for games like this and make the thread in ALL CAPS!
