P1 can be 512K, 1M or 2M (27C400/27C800/27C160).
*If P1 is 2M then some jumper must be set (JB3? didn't look into it. see kof95) and P2 should be empty.  First half of P1 is mapped to 0x200000-0x2FFFFF and second half is mapped to 0x000000-0x0FFFFFF.
*If P1 is 512K or 8M, then P2 can contain a bankswitched ROM (same type as P1 plus 27C322).  P1 appears at 0x000000-0x0FFFFF.  P2 banked rom appears in 0x200000-0x2FFFFF.
 
====V ROM====
 
V ROMs can be 1M, 2M or 4M (27C800/27C160/27C322).  Size of largest ROM is selected with a pair of jumpers and the other 4 should be left unconnected.  512K can also be used but only if there is one ROM and only the last used slot.

The only non-protected board that can bankswitch and use all V ROM space. Really common and very useful for homebrew stuff or converts.

P ROM

P1 can be 512K, 1M or 2M (27C400/27C800/27C160).

  • If P1 is 2M then some jumper must be set (JB3? didn't look into it. see kof95) and P2 should be empty. First half of P1 is mapped to 0x200000-0x2FFFFF and second half is mapped to 0x000000-0x0FFFFFF.
  • If P1 is 512K or 8M, then P2 can contain a bankswitched ROM (same type as P1 plus 27C322). P1 appears at 0x000000-0x0FFFFF. P2 banked rom appears in 0x200000-0x2FFFFF.

V ROM

V ROMs can be 1M, 2M or 4M (27C800/27C160/27C322). Size of largest ROM is selected with a pair of jumpers and the other 4 should be left unconnected. 512K can also be used but only if there is one ROM and only the last used slot.

Pinouts

Bankswitching is done with the LS74. It's not needed if the game isn't banked. Any write to an odd 0x200000-0x2FFFFF address will set the bank.

One of 4 V ROMs is enabled with a set of LS139 outputs. The pair of V ROM jumpers effectively choose a set of 2 NEO-PCM address outputs to input to the LS139.
