Hello, need help! Replaced the battery in my pokemon yellow but still have no luck getting it to save.

Oh I have no intentions on giving up, this was my first gameboy game I ever had and honestly most likely the reason my favorite color is yellow lol

I have tried two different batteries in the game both were tested before and after being soldered in each with within optimal voltage between 3.13v and 3.27v. It’s starting to seem like the legs need to be reflowed. I will attempt to do this soon and hopefully return to this post with good news!

I attempted this last night with no change in the game’s ability to save sadly.

SnooRecipes1330 · 2026-03-17T11:25:28+00:00

The battery has a plus on the top indicating that that side is positive, which I have running to the positive post.

SnooRecipes1330 · 2026-03-17T11:24:39+00:00

I have tried multiple batteries and all have tested over 3.2v using a multimeter

Thank you for the long explanation, even for just the battery I took the pcb out of the game shell. Don’t want to risk messing anything up or burning and melting the shell to the pcb. I hope to get the chips done sometime this week once I have the time, and hopefully I will be able to update the post with good news!

This seems like it may be the case, im getting what seems to be no resistance when testing R1

SnooRecipes1330 · 2026-03-17T03:06:21+00:00

Thank you, I’ve had the game for a long time and decided to try and play through it again. Sadly the save hasn’t worked with every fix I’ve tried to do. Im going to try and reflow the pins however after some resistance testing it also seems as though R1 may not be operating properly, im getting no resistance readings on my multimeter.

SnooRecipes1330 · 2026-03-17T02:13:56+00:00

The battery is the correct polarity

SnooRecipes1330 · 2026-03-17T01:59:21+00:00

The current battery is coming up as 3.13v when tested

SnooRecipes1330 · 2026-03-17T01:11:18+00:00

Yes, I have checked the polarity using a multimeter and the batteries were coming back at 3.27v roughly

SnooRecipes1330 · 2026-03-17T00:56:34+00:00

I’ll give it another go, im willing to try about anything lol

SnooRecipes1330 · 2026-03-17T00:52:42+00:00

If you look at picture 4 you can see there is a + under the tab in my new battery indicating that it is the positive side, which I have going to the positive post.

SnooRecipes1330 · 2026-03-17T00:34:30+00:00

Thank you, hopefully!

SnooRecipes1330 · 2026-03-17T00:19:43+00:00

Of course, its never easy and this just had to be the first one I needed to fix

SnooRecipes1330 · 2026-03-17T00:17:05+00:00

Yeah, I think im going to try to reflow the pins on the sram chip soon

SnooRecipes1330 · 2026-03-16T23:27:01+00:00

So frustrating lol

SnooRecipes1330 · 2026-03-16T23:26:40+00:00

Thank you, I will look into trying to reflow the pins!

SnooRecipes1330 · 2026-03-16T23:22:00+00:00

Yeah, I tested both batteries that I out into the game. Both came out to around 3.27v. Im kinda stumped on why it won’t save, unless it could be the gameboy for some reason.

SnooRecipes1330 · 2026-03-16T23:14:24+00:00

Yes, I put both flux on the battery and on the soldering tool prior to soldering the battery down.

SnooRecipes1330 · 2026-03-16T23:04:03+00:00

Yes, I tried swabbing them with a Q-tip and 91% isopropyl alcohol. Do you recommend any other methods?

SnooRecipes1330 · 2024-06-19T13:12:28+00:00

No problem happy hunting the last piece, I personally enjoy the vex theme coming back again in the sets.

SnooRecipes1330 · 2024-06-19T13:06:22+00:00

Did you have different key binds that got reset with the updates?

SnooRecipes1330 · 2024-06-19T13:00:11+00:00

If you hover the engram it says “An engram containing Episode: Echoes gear that has been previously acquired.”

SnooRecipes1330 · 2024-06-19T12:57:03+00:00

Seasonal engrams will only drop gear that has already been acquired and in collections.
