I bought a GBA SP motherboard in non-working condition that came with a free broken copy of pokemon sapphire. Apparently this copy of Sapphire "fried" the SP motherboard. I got the SP board working (it had blown the F2 fuse). I am new to all this so for the sake of learning I wanted to see if I could get this Sapphire working.
When I got the game it looked like someone previously lost a solder pad when removing the battery, and during the repair created a solder bridge on the sram chip. (View image "Original State")
I removed the bridge and repaired two broken traces. This fixed the shorting out issue and the SP will boot up with cartridge inserted but the cartridge is not recognize. ( See repairs on image "Trace Repair")
I noticed this pin on the SRAM chip. It looks like it doesn't go anywhere but any input would be nice. (View image "SRAM close up")
I know the issue could be anything, maybe bad chip, whatever, but I'm here to learn so anything input is appreciated, advice, theory, criticism, anything is useful. Thanks
