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 KZread 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!

the battery is standard or i need rechargable?

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!

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

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.

Does your iron have a temperature control? If so set it to max. Sounds like you do not have enough heat.

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).

Reversing the battery would very likely kill the SRAM chip.

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 :(

@TrackZero

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.

“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.
