Ever notice that the Donkey Kong cheat to finish the current screen only works on Rivets? It's called "Finish sub-level 4 Now!", because Rivets is the 4th type of screen, but it's the 6th on a full level (Barrels, Factory, Barrels, Elevators, Barrels, Rivets) So, you can can only skip one screen out of six. Not good.
I added the skip Barrels/Factory/Elevators to make this a universal screen skip function:
<cheat desc="Finish Current Screen Now">
<script state="on">
<action>main.pb@6290=00</action>
<action>main.pb@6205=30</action>
</script>
</cheat>
Sorry for the format. It really is much more usable with a key binding, so you'll probably want to use an old version of MAME with the old cheat format. Anyone know the last MAME version that had key binding working?
