Tiger Heli Arcade Pcb Graphic Issues with jamma adapter

Description

Tiger Heli Arcade Pcb Graphic Issues.
Was working great until one night i had been playing for an hour and stepped away for 15 minutes and when i came back the helicopter sprite was glitched as well as the helicopter at the title screen.  I bought a chip for it thinking it would resolve the issue but it didnt and its included with the pcb as well.  Its missing one leg/foot/ seperator on one corner but is still stable.  Sold as is working with graphical issues.  Jamma adapter included.
