Hey guys...I'm wondering why someone would solder this chip like this whether is was a fix or not...looks like the battery was replaced and then this chip was soldered on...the game doesn't work and to me it's clearly because of this soldering job...who has the knowledge to tell me if I were to remove this solder could this game possibly work again...or do you think I would need to replace the while chip...this is for uncharted waters so not a cheap game to replace....here are some pictures....thoughts??
