Thanks, added - though I've not duplicated for the clones which seem to be offset by either +4 or +2

Sorry, bumped old thread.

But any ROM codes cause ROM error around middle level.
In the official database based on 0.264, the following are ROM codes.

Hit Anywhere
Select Player Speed
Select Shot Speed

Also Wayder's database has ROM code called "Always get 100%".

Someone post about ROM error for 1942 with cheat.

Original poster misunderstand. It's not any BUGs. in-game ROM check routine detects that ROM is tampering by cheat system. So it's correct behavior.

Solution is simple, you don't use any ROM codes or disable in-game ROM check routine.
I post the codes based on the latter thinking.

1942.xml

Code: Select all

    <cheat desc="Skip In-game ROM Check">
        <script state="on">

        </script>
        <script state="run">
            <action>maincpu.mb@711A = 18</action>
        </script>
        <script state="off">
            <action>maincpu.mb@711A = temp0</action>
        </script>
    </cheat>

1942a.xml, 1942abl.xml, 1942h.xml, 1942b.xml, 1942p.xml, 1942iti.xml
