    Well, any help is welcome...Thanks. ;)[/quote]

    Some of your code is still not converted correctly. For example,
    Code:
    		btst	#7,($FFFFB00A).w
    That line is testing if bit 7 is set in art tile for Sonic. However in Sonic 2 Art_tile is not $A. Also,
    Code:
    		move.w	#$F380,Jumping(a0) is not correct either.  jumping is a Sonic Specifc variable.  You can use it, but i would use say, objoff_3C instead.  This line, 		move.l	#loc_19922,(a0) doesn't work in Sonic 2.  You will have to find another way of doing that operation.  S3K is not easy to convert if you don't understand how objects work.   Hopefully these few hints will help you.  Also, look at how objects work in Sonic 2 and try to find the same object in the S&k Disassembly and look at the main differences. The monitor object is a good start.

    In the S3K Disassembly, I removed the following line:



    Code:
    move.w	#$F380,Jumping(a0)


    Compiled S3K and the result was that the shield continues running smoothly.

    But if you remove it:



    Code:
    move.l    #loc_19922,(a0)


    He does not appear, only the works that is the Bubble Shield Bounce. It either say that this is the line that separates the bubble shield me ...

    As I understand it, I have to give a way to change this line to work correctly that is not in sonic 2? I will try ... Thanks for the tip Alriightyman
