FAULTS MISSING SPRITE CLOCK AND BAD Z80. REPLACED CLOCK WITH CORRECT 24.00MHZ AND FITTED 74HC CHIPS TO MATCH THE NEW CLOCK. BOOTLEG IS FITTED WITH SLIGHTLY FASTER FROM FACTORY THAT MAKES RASTER EFFECT ERRORS ANYWAY SO A GOOD UPGRADE. IT IS ALSO POSSIBLE TO UPGRADE THE SOUND AND GET SAMPLES WORKING, ANOTHER GUY HAS DOCUMENTED THAT, I WON'T BE GOING ANYMORE ON THIS ONE.
