Hello I recently purchased a working galaga 88 pcb, it seems to play great. The only thing I've noticed is that I can only set the difficulty(rank) at a,b,or c I can't set it to d or e the harder difficulties, I also can only choose 3,4, or 5 fighters(lives) not 1 or 2. Any ideas or anything I should look for? Ive searched all over google and had no luck. Thank you
