I made some attempts to reconnect board traces to no avail. I found a 3d print file for a replacement shell and I want to know if anyone's designed a replacement PCB that I can order on some service like PCBway. I'd prefer one that I can just transfer the ROM chip onto and I'll be good to go. Yes, I have a soldering station with both a heat gun and iron, flux, solder and a digital microscope and have the necessary skills. I've soldered BGA153 chips during Nintendo Switch repairs before, which are even more difficult to solder. I'd prefer a cloned PCB so I don't have to destroy another cartridge to fix this one. If there isn't an open source cloned PCB, how would I design one? I'd prefer a tutorial that uses KiCad as that is the best in terms of FOSS I've heard.
