I've been trying to make an 64MBit (8MB) game using 2x29F032 on the following board: SHVC-2J3M-01. The problem is, the TSOP Adapter is DIP36 but the PCB only has 32 pins for each MaskROM, so I A20,A21,A22 and Pin 36 (VCC) are floating.
Cart #46 and#48 are not available and the decoder is a MAD-R.
MAD-R is connected as follows:
Now how do I connect A20,A21 from both 29F032? Do I need to modify MAD-R, too?
EDIT: The donor was a Seiken Densetsu / Secret of Mana
EDIT2:Solved. Desoldered MAD-R and connected as stated in this topic:
