Hello!
I'm trying to program the game 7th saga but so far no success, I have the cartridge in the Japanese version and I'm trying to program the American version,but until now did not work.
the board: SHVC-2j3b

it comes with 2 Mask ROM, 1 CAT534010A (512k) and 1 CAT538010C(1MB).
I tried two methods

I replaced the cat534 for 27c801 and cat538 for 27c801
wires coming out of the pin 31 to 24 and 24 for 31 in both.
but it did not work, only black screen.

so I tried:
I replaced the cat534 for 29F040 and cat538 by 27c801
Pinout for 27c801
wires coming out of the pin 31 to 24 and 24 for 31.
Pinout for 29F040
I found an article explaining the pinout of this cat534 and follow:

wires coming out of the pin 1 to 30,
2 to 1,
30 to 24
and 24 to 2

testing appears the Enix logo in a pink color and freeze in the black screen.

Can anyone help me with this?


Sorry for bad english.
