Replaced save battery and reflowed pins, but crystal is still not working
So when i was playing my crystal version, I noticed that when i was playing it in my SP and slightly tapped the cartridge, the game would crash (brand new save battery, it was installed properly and saved just fine.) I cleaned out the GB switch in my SP, but that didn't fix the issue. I read online that this can be caused by cold solder joints, so next i reflowed the SRAM and Rom pins and that fixed the issue for a few weeks, then the crashing issue started happening again.
i then reflowed every single pin on the board, and now the game won't work with my non AGS-101 SP since it wont even boot to the gameboy logo, and for my AGS-101 SP it turns on and works, but it has some graphical errors with moves in game, and the game now will not save. I am at a loss at this point and could use advice. Here are some pictures:

Clean those connector pins - that was probably your only issue to begin with
91%+ isopropyl alcohol and a cotton swab or toothbrush
That was the first thing I did, and I cleaned them multiple times throughout this whole process
The photo makes the pins look very dirty - try a white pencil eraser (or soft pink) and then another round of IPA
