You'd need the knowhow and one or two PLD (16V8 or 20V8.) Unless you are going to register map your HiROM switch/enhance the BIOS, you'll need a physical switch and do a manual reset to play.
LoROM shifts the address bits right after A15 (disconnecting A15.) a 16M game uses A16..21 instead of A15..A20. HiROM uses the full bank width ie A0..23 = A0..23. |
