So i bought a gba cart from ebay and it doesnt want to save. I got a small CR1616 battery and soldered it to the points but it still does not want to save. Anyone want to take a look at the pics and let me know if i messed something up or is there something else i am suppose to do on the PCB? Bridge something? cut lines?

There is this guy on youtube that explains how to do it but his PCB is different,

A couple things here.
1. That is not an official Nintendo cartridge. I don't expect it to work at all.
2. From the looks of it, these degrade VERY fast depending on play habits in general.
I would expect the developer to know how their own cartridge works, but it is not official, and I doubt normal methods could fix it.

EDIT:
3. Wouldn't this technically be cramming a cartridge? If those are all GBA games, that seems like it wouldn't work. A Gameboy game is like 14-ish megabytes, and the ending result of 369 games would be 5166 megabytes. I would expect saves to be loaded from a MicroSD.

Well its actually a scam, those are not all gameboy advance games. Its more like 10 GBA games on this thing and the rest are shit homebrew games made to look like other old Sega/NES games that totally suck. but there is a few nice GBA games on this so i wanted to fix it to make it work normally.

This cart doesn't seem to be supporting a battery.. You should do more research before actually starting to solder the board! I'm not too familiar with GBA carts, but I know that the cartridge board and the chips will have to support a battery if it's going to work!
