Yeah, must be. Boy do i feel dumb. I was worried my gameshark may have been to blame!

Turns out you guys were right. Though it's funny as every video/picture/original battery i saw was positioned the opposite way. Didnt even think to check the polarity of the battery i had.

Had a bit of a google search and every image showed the top tab facing downward.

Wow if it is ill feel very stupid. Though i'm almost certain thats the way the old one came off!

I dont think im going to be that lucky. I matched it to the direction of the old battery, and im pretty sure the negative side is that with the tab soldered over the top of the battery.

Sorry, posted a picture in the wrong thread. The joints dont look fantastic, but i reseated it about 3 times, adding a bit of flux and even though they now look perfect, it still wont save. Cart is in good condition. Always worked. Obviously the battery died recently and i decided to replace...

Annnnd it worked. Thank you so much. Now to figure out why my pokemon crystal wont save despite changing the battery.

That is GOLD! Thank you so much i have been pulling my hair out for months. Now i can get two speeds in! For me it's just to play the Pokemon series again. I want it to be fast, but with the ability to drop back to normal speed should there be anything i want to play 'normally'. I purchased...

So i changed the battery in my crystal cart. Soldered, resoldered. Removed, soldered again, and nothing. Battery shows 2.9v. Game will not save at all and im not sure why. Is there a way to troubleshoot? Thanks

So i managed to get the ceramic top off quite easily. Became very clear to me how it works. The crystal was in tact. I ended up tearing it when i tried to re solder a wire. So now it works, great!! Though i cant switch between clocks. If add another crystal for normal speed, how do i wire that...

"Now solder a wire from one spot on the original crystal to the first point on the switch. Next solder a wire from th other spot on the original crystal and solder the other end to a lead on the new crystal. Lastly, solder another wire from the other lead of the new crystal to the second point...

You have confirmed my suspicion. I removed one on another board and couldn't understand why the black ceramic top piece had metal tangs? So it is just a tiny crystal within the ceramic? So essentially the clock wont work unless the factory crystal is removed, or at least disconnected from one...

Oh thank you so much. It's a miracle! So if i remove the crystal, wont it only clock one speed? Is the crystal the black top part?

Im never going to get to the bottom of this, am i? :(

Have you tried cleaning the sonic contacts?

If a pot adjustment yields few results, would this suggest that the laser is almost dead? My DC reads some GD discs, some of the time, and some CDR's all of the time. For example, a certain GD disc will not boot at all, it attempts to load for a few seconds and returns to the DC menu screen...

Maybe its just a bad connection on the side of the crystal?
