 Fine, Tweaker. You asked for it.<br><br>Here&#39;s more or less prototypical code for my variation on the Sonic Chaos GG Tails Flying Code. However, I&#39;m not incredibly familiar with all the RAM addresses, so I&#39;ll at least need to check that.<br><br>check if button up is pressed (I know that this will require some sort of bitwise function, but I&#39;m not sure to set it up), BNE to RTS <br>check if button a, b, or c is pressed, BNE to RTS (same)<br>display frame (tails flying) (move --, &#036;(--).w) [I don&#39;t know what frame is which]<br>every second add &#036;A9 to player y position and add &#036;A9 to some unused value in RAM that is equal to zero (gradual -- how many refreshes of processor in one second?) (I could do this -- IF I knew how the game handles jumping) (add.b #&#036;a9, (&#036;FFFxxx).w) <br>once second RAM value equals &#036;251, display frame (tails jumping/falling) (CMP &#036;FFFxxx, &#036;#251 BRA to code MOVE --, &#036;(--).w)<br>rts
