Never having had a GBA growing up (or really any gaming system), I recently decided to delve into the retro scene and try to reshell a GBA SP. I bought a board and shell off Aliexpress and a few reproduction cartridges. (VERY) stupidly wanted to test the repo cart without finishing the shell and ripped off the cartridge slot!!!!

After much profanity and months before I could stomach looking at the thing, I buckled down and spent too much buying tools/supplies. Many many many many many Youtube videos later, I finally managed to reseat the slot and connect the damaged pads.

Just thought I'd share that it's possible, having started only with very rudimentary soldering skills.
