Just a Question How can I make Tails Fly in Sonic 2 Rom Hack

[GamingUnleashed]

I wanna do port his flying code from sonic 3 & knuckles & port it to sonic 2 but i don't know where his flying code is & i don't know much about changing out stuff to make the code work in the game so I'm just wondering how i can port it over

I don't know where Tails' flying code is, but you might be able to find it by comparing the code of Tails' object from Sonic 2 and Sonic & Knuckles. Chances are that the flying code is in its own function, so there would be an extra bsr.w or jsr instruction that calls it.

To port the code would likely require dehardcoding things if they haven't been already, such as SST constants ($A(a0) to x_pos(a0) or something like that) or RAM labels (($FFFFFA23).w to (Camera_X_pos).w or something similar). Once that's done, the SST constants and RAM labels need to changed to their Sonic 2 versions. The Sonic 2 and Sonic & Knuckles disassemblies have similar naming schemes, but there are still some differences. Code labels and function names also need to be changed to their Sonic 2 equivalents.

Once that is all done, should be ready to insert into Sonic 2, calling it with bsr.w/jsr in the same place as it is in Sonic & Knuckles. You will also need to port the flying SFX, sprites, and animation.
