- How to Replace a Super Nintendo Cartridge Save Game Battery
Do you have a SNES and some original #Nintentdo game cartridges? Some of them may have a battery backed up RAM for your saved games. You can swap out those old batteries with a nice new serviceable battery solution!

I use the same battery holders. Grinding the the nubs, and the entire holder an additional millimeter and filing down the negative terminal is the sure fire way to have the holder sit in flush withing the shell of the cartridge, thus eliminating stress on the PCB that would cause it to angle ever so slightly to the connecter in the system.
This is a great video, cheers.
Battery holders are always a sod to sodder mate.
Whilst I'm out of RUclips action I'm really enjoying your videos. Thank you Doc.
Mark, glad to be helping you pass the time, I am sure you have a lot of creative energy to spend! I have quite a few carts, I'm trying to think of a way of figuring out which have batteries without opening them all up!
@@backofficeshow If you have accurate scales you might be able to weigh them?
@@MarkFixesStuff I have something else. You will really like what I've got for this 😛
@@backofficeshow X ray spectacles?
@@MarkFixesStuff I was going to use a divining rod but your way is much better
Just was wondering about the product RMC reviewed some time ago (The DB-15 to USB), would it be possible just to hook up a DB-15 port to the PCB, and run it as external source? Since i'd like to not modify the joystick. I tend to, mildly break some of the components when i open them by accident xD
It sounds possible depending on how the joystick is wired up. If you look on my website you can find the manual and how to hook it up, there is a good chance this will work!
@@backofficeshow Good lord this was a really fast response! I'll look into the scheme of pinout on the controller. It's a interact pc saber pro, if it means anything to you :D Thank you!
@@HoboVibingToMusic no problem
the battery is standard or i need rechargable?
3:41. Im doing the same thing for an upcoming video for changing the batteries on a stack of N64 carts, and i have the same problem with a lack of batteries. Mine are still incoming from china, so filming is halted for a few weeks.
Don't lick em!
Most N64 carts use EEPROMs rather than SRAM, I think there was less than 10 games using battery powered saves. I was worried about my Goldeneye cart until I found it was an EEPROM gamesave!
I thought the N64 had a separate memory module that lived in the console itself? I might be imagining that 🤔
@@backofficeshow You may be thinking of the module which plugged into the top of it, that was just a RAM expansion. It also had memory cards which plugged into the controller. But for game unlocks etc it saved to the cartridge (eg the Goldeneye cheat unlocks).
No demo of what it looks like booting up the first time after replacing the battery?
I did this for my partner's Pokemon Blue cart. Game sadly lost already, so I just de-soldered it and inserted a new one. It worked without a hitch. Basically no save game data was present on boot and I was able to save. She doesn't play it anymore so it just sits on a shelf in our collection of portables now.
The boot is exactly the same just minus any save game files
Careful now, don't want to upset those Gallagher's. Especially that Liam one. 😄
I replaced the battery on donkey kong country with a brand new battery and when i tried to play the game for the first time i got a message that says it cannot play game on a device that makes copies. I turned off my super nintendo and tried again. It plays the game but it does not save. Any advice on how i can fix this problem?
I would first check the voltage of the battery while it is still in the cartridge and then double check everything is correctly soldered, no bridges etc.
Ok thanks
@@extremo4602 Did you fix it?
@extremo4602 Did you fix it?
Do you loose the Save Game if you dont give voltage to the cardridge ?in the time you replace the Battery?
Yes
@@backofficeshowok this is Bad i want to keep them :)
@sulisgiangu9147 you can solder another battery in parallel to keep it alive while you change the main battery
Ok Thank you :) i will Check it;)
Does the cartridge price decrease with battery replacement?
Only if you make a mess
@@backofficeshow Haha! I didn't. I fixed the battery and it's working now. Ty for the video.
Reversing the battery would very likely kill the SRAM chip.
Dunno, they have a beefy looking resistor in series. It would probably actively wipe it though.
with 1.5v? now I'm curious.
@@Kyrazlan 3V, it's a lithium battery. I've seen Casio calculator with a blown IC, because someone inserted the 2 AA batteries reversed.
i'm 2 hours in and still couldn't de-solder the battery. What i am doing wrong? Beginner here
Does your iron have a temperature control? If so set it to max. Sounds like you do not have enough heat.
Noyce!
My batteries never come off that easily D:
You only get to see the one cart I didn't destroy 😂
Did it work?
Yeah
eon thx flux
I can't overstate my jealousy that you UKers got the sleek "Super Famicom" style consoles and cartridges, while we Americans got ugly bricks lol
cool project!
I always felt sorry for your horrible purple bricks. I really never understood that.
I for one love our ugly bricks lol.
I have some famicom games that still save fine. 80s baterry tech was bloody amazing. I hope Elon Musk is taking notes.
“Blowing” into the cartridge isn’t what you actually want to do. You want to use “hot breath” and the water vapor will condense on the metal contacts creating a better connection.
I came to the tutorial happy in the beginning thinking you would use the same holder of the original battery judging by the replacement battery you had on the side. Then boom ! What a disappointing jump cut... time wasted :(
That'd be a bad idea, the original holder is spot welded to the battery. You wanna just replace the entire holder mount to the board.
