Repairing Metal Slug X

This guide is for repairing Metal Slug X carts with dead Altera MAX chips. Either the game ROMs can be transferred to a PROGBK1 or the dead MAX chip can be removed from the PROGEOP. Both methods need a hacked ROM which is linked at the bottom of this page.

A. Using donor PROGBK1

1. Set jumpers correctly on BK1 board using this as reference: [1]
2. Move all ROMs from the EOP (except for P1) to the corresponding places on the BK1
3. Replace the BK1 P1 with a 27C800 containing the hacked ROM image

B. Fixing the PROGEOP

(todo)

• remove MAX
• replace P1 with hacked ROM on 27C800
• patch D0-D7, /E /G etc.
• get ls74 and ls08 hooked up
• get ls139 hooked up for V ROMs
• whatever else, lots more to do compared to BK1 donor swap

P1 replacement
