add dump of i8751 '317-0112' at location c2 to 'goldnaxe2' set. chip was faulty, some bit errors, internal checksum fails. still using simulation for now [Caps0ff]

(the code looks to be mostly the same as the goldnaxe set, not even offset, but unused garbage areas have different fills so tracking down exactly which bits are bad is difficult, as they're not neccessarily all in the used code)
