/*************************************************************************** Gun Dealer memory map driver by Nicola Salmoria Yam! Yam!? runs on the same hardware but has a protection device which can access RAM at e000. Program writes to e000 and expects a value back at e001, then jumps to subroutines at e010 and e020.
