its completely dead. it does nothing. the only thing i see is it looks like it has had 2 things replaced at l35 and L36. its a shitty solder job too. i have transferred the roms to my off road challenge board and they work perfectly on that board.

fixing repair jobs done by others without the skills or equipment is usually 2-3 x the work.
Look over that board really well in that location for missing traces and since that board is completely dead, I would look at the voltage rails going to them chips.
