Code: Select all

	<cheat desc="Skip RAM/ROM Check" delay="0">
		<script state="on">
			<action>temp0=maincpu.mb@017f</action>
			<action>temp1=maincpu.mb@01e6</action>
			<action>temp2=maincpu.mb@027d</action>
			<action>temp3=maincpu.mb@0361</action>
			<action>temp4=maincpu.mw@0364</action>
		</script>
		<script state="run">
			<action>maincpu.mb@017f=00</action>
			<action>maincpu.mb@01e6=00</action>
			<action>maincpu.mb@027d=00</action>
			<action>maincpu.mb@0361=00</action>
			<action>maincpu.mb@0364=00</action>
		</script>
		<script state="off">
			<action>maincpu.mb@017f=temp0</action>
			<action>maincpu.mb@01e6=temp1</action>
			<action>maincpu.mb@027d=temp2</action>
			<action>maincpu.mb@0361=temp3</action>
			<action>maincpu.mb@0364=temp4</action>
		</script>
	</cheat>
It works, but shows a ROM checksum warning but it continues anyways, You can safely enable another cheats with it and it won't bother about bad checksum and getting stuck in the boot screen, thus, it lets the game boot in about 1 second (pretty less than the 12 seconds the checksum routine lasts). You have to enable and reset to test it (Unless a "preenable" feature in the new cheat engine is implemented)
