So a while back I bought some faulty boards, some of which were beyond repair. In them was this Lup Lup Puzzle board that has had a repair attempted at some point.

The game boots and plays, but there are graphical glitches and a rhythmic buzzing/reverb sound, I've tried to capture the glitches in a couple of the pictures - Black lines on the far left of the screen and a line through the title screen. Looking at the board all seems well apart from one chip, a NKK N341256SJ-15 8J045020 9824 . This is where the repair was attempted and from what my very unknowlegable eyes can make out, there was excess flux left on the board and underneath the chip looks to be corroded. Is there anyone that could possibly take a look at the board for me and potentially repair it?
