This is the nicest board in my "might be fixable" repair box and I can't make any headway towards fixing it at all. I am out of ideas and I thought I should bring it here for more.

3. I replaced a resistor that looked suspect.
4. I think this is the simpler Turbo Force hardware variation of this game.
