SAROM Board Dev? 28 to 32 pinout

[N340]

Looking around and I am having trouble finding an answer.

I had a few spare copies of Dragon Warrior so thought I would use one to make a DEV board for an MMC1 with Battery and WRAM. Only complication I am running into is the SAROM board is 28 PINs PRG not 32 like most of SxROM boards. Anyone know of a pinout for the PRG and CHR so i can wire a 32 pin adapter?

Thanks, for some reason that portion of the wiki seemed to elude me.
