oh boy.. generic 8liner board. Best of luck, you may have to get some other 8 liner board unfortunately. Post a couple pics of the board, and any numbers you can read on the "hot" chip..(if your talking burn your finger hot yeah something bad happend)
mabye youll get lucky and just be able to replace whatever it is, however if its something game specific like a rom you are probhably sol.
It nay be worth your time to check the +5 volts. If its too low it may stop the game from booting, if its too high it may explain why your board failed.
