Curious question about perfect ports and IC-Constants.

[Aura Sphere]

So, in my game I have Marth on himself, and ported over R.O.B., Luigi, and Peach. I have Ike on himself, and on Dedede and Olimar (Dante moveset). I then have Sonic on himself, and on DK and Lucas. I have codes for Wario to have Marth's IC-Constant (Mewtwo over Wario) and for Dedede to have Ike's IC-Constant (not using a perfect port module). But I have Sonic over Lucas and Ike over Olimar with a perfect port module, no IC-Constant codes, and they have their AAA jab. Olimar used to be using the module that came with Dante over Olimar, until I used the perfect port module for Ike and just used the Dante over Ike hack on Olimar. Works better.

I want to port Sonic onto Kirby, but would I need the IC-Constant code? If I use perfect ports for my Sonic over DK, Ike over Dedede, or the others, would I need the IC-Constant code? I have 2 active, and if I use any 3rd one, one of them stops working. What do IC-Constants affect? I only noticed it affecting the AAA jab combo, and nothing else. Nothing bad has come of Lucas not having Sonic's IC-Constant or anything. Do I really need the IC-Constant codes with a perfect port? Aside from no crawl or normal jump codes I'm guessing, but then "Sikver over Luigi" and I think "Project Melee Mewtwo over Lucario" didn't use the no crawl codes, but they didn't crawl. Idk how that works exactly. I just wanna know if I need any IC-Constant codes with perfect ports. Anyone who can answer this, thank you!
