Pokémon Emerald Game Problem
So I bought the Pokemon Emerald cartridge(The previous owner glued a new battery with tape...). When I started the game I've noticed that the start screen logo was messed up also some other graphics were missing from the game. For instance I couldn't see the three pokeballs in the beginning when it was the time to choose my first Pokemon. As soon as I saw that I've opened the cartridge and found some corroded pins and traces(Some of them missing). The RTC IC had a missing and corroded trace.
I've cleaned them and re soldered the Rom and Flash Ic's, but nothing changed. Could it be that the ROM is faulty or something else?
