Conversion SF2' to Final Fight (CPS1)



An other CPS1 conversion. This is the US version of the game.


1) Material needed

1.1) If you use a 91634B-2 B-board (EPROM)
- 6 * 27C4096 ROM (4 for the graphics and 2 for the program)
- 1 * 27C010 ROM (audio)
- 1 * 27C512 ROM (audio)
- 1 * GAL16V8 (PAL)

1.2) If you use a 91635B-2 B-board (mask ROM)
- 4 * 27C400 ROM (graphics)
- 2 * 27C4096 ROM (program)
- 1 * 27C010 ROM (audio)
- 1 * 27C010 ROM (audio)
- 1 * GAL16V8 (PAL)

2) ROMs and PAL burning

Now it's time to burn the files on the appropriated devices.

2.1) If you use a 91634B-2 B-board (EPROM)
- ROMs 01/02/03/04//22/23 => 27C4096
- ROM 09 => 27C512
- ROM 18 => 27C010
- FF_PAL_1A.jed => GAL16V8

2.2) If you use a 91635B-2 B-board (mask ROM)
- ROMs 01/02/03/04 => 27C400
- ROMs 22/23 => 27C4096
- ROM 09 => 27C512
- ROM 18 => 27C010
- FF_PAL_1A.jed => GAL16V8

3) ROMs installation

All SF2' ROMs must be removed from the B-board.
The PAL named S963B at position 1A has to be removed too.
Double check you've put the devices the right way (the silkscreen should help you)!

3.1) If you use a 91634B-2 B-board (EPROM)
- Install the ROMs in the corresponding socket (ROM 01 in socket 01, etc.)
- Install the GAL16V8 in position 1A (where the S963B was)

3.2) If you use a 91635B-2 B-board (mask ROM)
- Install the ROMs 01/04/05/08/09/18/22/23 in the corresponding socket (ROM 01 in socket 01, etc.)
- Install ROM 02 in socket 03
- Install ROM 03 in socket 02
- Install the GAL16V8 in position 1A (where the S963B was)

4) Test
