Years ago, before I learned how to replace an R/S/E battery without a soldering iron, I tried to replace my Emerald battery via soldering. The plastic ring around the old battery, which I was instructed to remove with tweezers and put back on the new battery, was damaged, so I "created" a new one with electrical tape. My dad assisted me since I had never soldered before, and while the instructions I was following didn't use it, he suggested we use soldering paste, and so we did. The result was a game that is completely unrecognizable by my GBA. Here is a picture:
Does it look like my game is ruined, or can it be "cleaned up" by a solder vacuum or by some other means, and a new battery put in without soldering?
I'm posting this as a thread instead of in the SQSA since I feel it may be a bit too complicated for SQSA, and I'd like to get multiple opinions on it if possible.
Thanks!
