This forum is for posting M.A.M.E. Work In Progress "Arcade"cheats that are not quite ready for the prime time. If the cheats are buggy or the cheat descriptions are non-standard then please post them here. Help maybe given but there are no guarantees and they will only be added to the cheat file when the cheat file maintainer is happy with them.

Current "invincibility" doesn't work against some firearms (cup, cake, pie etc).
"no hit" disables these firearms but you can't push the stone after round 50.
And "invincibility" separates into "on" and "off" codes but current cheat engine allows you to merge these states.

Code: Select all

<cheat desc="P1 invincibility">
  <script state="run">
    <action>maincpu.pb@1084b0 = 08 | (maincpu.pb@1084b0 band ~08)</action>

  <script state="off">
    <action>maincpu.pb@1084b0 = 00 | (maincpu.pb@1084b0 band ~08)</action>
  </script>

I find "infinite time". If you set this value as 0x0001, devil will appear soon.

Code: Select all

This game has two worlds, normal (round 1-50) and another (round 51-101) and you can see true ending after round 101.
Unfortunately, you can't select another world via current "select starting round" because the count of round is the same (eg, round 2 and round 52 use the same value 0x01)
Current world is maintained by another flag and I find it. It's better to set the follwing code before start the game (eg, after inserted credit).

Code: Select all

<cheat desc="another world">
    <script state="run">
        <action>maincpu.pb@105b3f = 01</action>
    </script>
    <script state="off">
        <action>maincpu.pb@105b3f = 00</action>
    </script>
</cheat>
How to go to another world is as follows. "unlock secret key" I posted will be easy key find.
Image
Tap orange target several time in round 1 then get secret key and enter the gate to go to secret room.

Tap orange target several time in secret room then get secret key and enter the gate to go to password room.
