Easiest way you can find out is simply use these:
1 5343-12389-00 e prom 1 meg 27010 150NS
3 5343-12881-00 e prom 27c040 4meg 120nsec
1 5432-12726-00 ic ee prom pot x9503
1 A-5343-50020-1E prom assy-U6-rev 9.2
1 A-5343-50020-6E prom assy-U14-rev L2
1 A-5343-50020-7E prom assy-U15-rev L2
1 A-5343-50020-8E prom assy-U18-rev L
and now either look at the part numbers on your other game to see if they are the same (or google compatibility between the two part numbers) or download the manual for the game in question to get the chip part numbers. Typically the 1meg and 4 meg will work fine however that 4 meg may require a resistor change on the board.
