1MiB P1 ROM

16bit ROM(s) containing byteswapped 68k binaries in cartridges.

Sometimes, two 8 bit ROMs are used as a second P ROM (called "SP1/2" or "EP1/2").

Unbanked, the maximum size is 1MiB. Some games use bankswitching to use 2MiB and bigger P ROMs.

Some cartridges use have an NGPC_flash_board soldered in instead of a mask ROM.
