Attack speed up code seems to work for both players but require more test.

This code enables multiple jump in air. The jump distance is depending on the time of pressed jump button from normal jump to moon jump.

Also no-hit code. this code seems to work for both players.

    </script>
</cheat>

But this game has ROM check at boot. So you need to prevent from an error when you use ROM code.

"walk speed" : Added new.
"multiple jump" : Rewritten routine.
"no jump wait" : Added new. This game has "wait" between pressing jump button and starting jump. This code ignores "wait" so that character jumps soon.
"sound test mode" : Adjusted address and fixed comment.
