Topic: Have you ever had a cartridge based game's batteries die before?

I mean a game that had battery back up to save game data. I never have known of one to quit working but I suppose they would eventually.
My original Zelda cartridge still saves and It's a freaking fossil. It must take forever for the batteries to actually die. Good thing we have VC in case it ever happens.

yep. I have a copy of Super Mario World that died -- I'd have to leave the SNES on if I wanted to complete a game over multiple sessions. this was years before the Wii hit, though... thank goodness for the VC, because i love the hell outta SMW :3

Those batteries are just ordinary batteries, and can be replaced by methods of soldering.

They must be the longest lasting batteries in existence. I wonder if they drain faster based on how many times you made a save file?

Those batteries might just last longer than the actual Virtual Console service

aLttP and Wario Land 3

They can even be replaced by simpler methods if you can't solder.

If one wants to be able to open Nintendo carts, one needs a 3.8mm security bit tool or holder.

In case of the NES and SNES batteries; they are ordinary CR 2032 ones, available in most shops and super markets :

The Game Boy (Color) ones use a CR 2025, although a CR 2032 may be compatible too.

Since the save data of old games are only a few kb's in size, the energy usage is very very limited.

I never have which is kinda surprising.

My Zelda 2 batteries stopped working a long time ago. After that i exchanged the cartridge to "Sword Master". Zelda 2 was better even without working batteries...

I've never had a cartridge battery die on me, personally, but I did buy a copy of Pokemon Snap online that ended up having a non-working save battery. Luckily I can still complete that game in just a few hours, but it's still annoying.

The batteries of two of my favorite Gameboy games - Donkey Kong '94 and Super Mario Land 2 - died a year ago.
The worst part is that it made them completely glitchy; Super Mario Land 2 has random sprite glitches and freezes and Donkey Kong '94 screws up at the save file screen.
I can still play the game but some events like moving ladders, high voltage cables and switches don't work anymore.
It's really crazy.

Also the battery of my Pokémon Silver Version died.
Oddly enough the battery of my Pokémon Gold Version, where I caught all 249 (no Mew or Celebi) without cheats still works.

My brother's Zelda II. The file died on me in the last dungeon before I could finish it for the first time.

Not yet.

Nope

i dont know if this is from the batteries dying or something else, but my Advance Wars 2 cartridge refused to save after a while. it was a dark day

Miraculously, no. Super Mario World (which one of my cousins loaned to me), Donkey Kong Country, Donkey Kong Country 3: Dixie Kong's Double Trouble, and Super Mario All-Stars never had the battery die, and one of my older cousins (who loaned those games to me with his SNES console in December 29^th of 2008) has had them for as long as I remember. Perhaps it's because I keep playing with this those games.
The SNES games that I ordered on eBay that included saved data [Ys III: Wanderers from Ys, Arcana, SoulBlazer, Brain Lord, Illusion of Gaia, Equinox: Solstice II] work perfectly fine.

Nope. But that's because I don't own any carts with batteries (Unless Original GB and GBA Carts use batteries for saving, in which I am wrong).

I think my Bomberman Hero cartridge is slowly dying. Sometimes it erases all the files and they come back later.

What's amazing to me is that all of my NES and SNES games still work, as well as my GB and GBC games.

I am amazed my original Zelda and Zelda II carts still save fine. The only cart battery i've had die on me thus far is is one of batteries in my GBA flash cart (it has two), so it will keep games written to the cart, but not keep game save-states.
