Using 1J3M you have to rewire the MAD-1 properly to act like LJ3M (Tales of Phantasia board).
Just solder in the 2x32MBit EEPROMs like you normally would except each /OE lines. (You really don't need pin 35 (A22) here anyway).
Desolder the MAD-1 completely and lift pin 1,12,13 and 16 and connect it like this:
Pin 1 -> ROM1 /OE
Pin 12 -> SNES A22 (Cart#47)
Pin 13 -> SNES A23 (Cart#48)
Pin 16 -> ROM2 /OE
Thanks for this, I'll try it out soon (need to use the desoldering tool at work tomorrow hah).
I have two questions, though:
1) Where did you find the pinouts for the MAD chip for ToP, and would I be correct in saying the MAD chip is wired the same for all HiROM boards, and similarly all LoROM boards are the same?
2) After posting this, I looked back at the board in the original post, and it seems to be also a 1J3M board, unless I'm not seeing it correctly. Why did OP not have to rewire it like that?
And thank you so much for the help. This game has been on my list for a long time.
