This thread is for discussing the technical aspects of modding SF4AE. It is not for submitting skins. Do that in this other thread, instead.
If you’re just getting into modding, hit up the tutorials on the modding wiki. Most everything still functions similarly to vanilla SF4, but the engine doesn’t use emz bundles for costumes/colors anymore.
I will update this first post with some frequently asked questions as they arise, so please read it before asking.
Someone else got the jump on us! D: Moveset swaps already when I’ve just started testing move changes…
Anyone know how he did it?
@d3v
Thanks!
@orgolove
I would guess they just renamed/replaced the bcm and bac files. I’ll double-check once the game is actually released.
He just renamed Oni’s skin and put it in Cammy’s folder. (under hp bar you have the name) hence the deformed face (he didnt thought of swapping the face file now separated in SSF4AE)
Kinda the easy stuff people already did with SF4 (were the first mods actually).
I would do it the other way and put the moves in the files of another, then you would have the matching name 
Capcom really made it easier here you can swap whatever you want by just renaming the files.
@sensibeat
good eye, catching the name
Steam should let me download the game this afternoon, so I hope to dig into some of the things we’ve discussed elsewhere.
I made the game freeze because I missed the fact the bac and bcm files are in their own folder: dlc/03_character_free/battle/regulation/latest/
(those are the files for the moves after AE “regulation”)
You can find other bac and bcm files in the character folders (resource/battle/chara/), but those are SSF4 files, so they don’t apply while playing AE.
AE characters miss the clg files as they are for the challenges and those characters don’t have any.
It looks like you can really swap any files from a character folder to another and just rename them even the vfx.emz
Will you recognize whose moves did Juri get?

I changed every files from JRI.cam.ema to JRI.vfx.ttex.emz but JRI.fce.ema, just by renaming the files in the resource/battle/chara/JRI folder.
Then I changed the bac & bcm files in the dlc/03_character_free/battle/regulation/latest/JRI folder.
Man, that sure is easier than it used to be! I guess monkeyface is a thing of the past
So, if it has bac/bcm files from Super, I guess we can use the Super version of movesets. Have you tried any vanilla bac/bcm replacements yet?
more
@hunterk
No I haven’t tried SF4 Sagat vs SSF4AE Yun if that’s what you mean.
I’ll let you test it, I know you want to.
@Thirtyfour
More? you mean you haven’t found who owns the moves I swaped?
No! Not the head bite!
That’s quite awesome. Good to hear - thought there was some special index file/name we need to change, like in vanilla.
Thanks! I’ve always wondered how T hawk’s ultra 2 would look when done by a smaller character.
Though I really get discouraged by all the hate I get after spending weeks modifying moves, making videos, writing up a list, etc…
Is there any ssf4ae cmm (SSFIVae Custom Mod Manager) program, or something like that, something that automatically changes modes in super street fighter 4 arcade edition???
@orgolove
What I did is easy and can’t be compared to what you did on Vanilla, I just swaped the whole moveset.
I didn’t edit the moves of the character nor added any characteristics (juggle etc) to them like you did.
This is still a tough task. I tested perl on SF4 files, I understood the basics of editing the moves but it seemed so long to do.
If pearl scripts don’t work on AE files directly, you could try to rewrite a Vanilla’ish cmn.emz from AE files, tho you would have to do it manually as I don’t think kensou’s tool support those files (I had issues with col.emz files containing more than 4 files). Then after editing it you would have to cut it back into AE files.
Don’t listen to haters, I had people cursing me for my bad playstyle when I uploaded videos IA vs IA just to show costumes …
@draskozli
I don’t know if Leogansky will make a new one for AE.
Me, Anotak and Polarity are working on SSF4AE modding. Developments are going really fast rn, and Anotak already got tools going for editing almost everything in the .bcm. I’m kind of not that involved with that because I’m not as good at actually reading hex apart from areas I already know i’m just going “oh cool what does that do oh shit”
There’s already progress on adding and changing cancels (the cancels are what it cancels to, so you still have to add in cancels for moves that don’t usually have it.) as well as some early stuff on meter editing, what motions a move uses, what inputs it uses etc.
So far, SSF4AE is a lot easier to mod than vanilla, but that might just be because Anotak’s on board again.
BTW: SSF4AE Koryu is already in progress: http://www.youtube.com/watch?v=Ui3DTYHjjk8
I’m glad to hear you guys are back at it. Over in the vanilla skin thread, Recycler posted a couple of links to a chinese forum where someone had already edited the move inputs, so you might take a look at that if you get stuck. Are you guys going over things in a public thread? If so, I’ll lurk there, too.
I’ve been trying unsuccessfully to get vanilla bac/bcm into AE, but it’s crashing on me. I didn’t spend much time on it, though, so maybe I’ll get something going soon.
I also unsuccessfully tried stealing some of Oni’s “emission” materials to give other characters the same sort of fire effect on their bodies. No crashes on that one, but no effect either. Related: it appears that since the emz bundles are gone, the game doesn’t really care about the size of the *.obj.emm files, so I think you can just insert as much hex data as you want without it prompting a crash (i.e., no more worrying about overwriting/inserting). I’d like some verification on that, if anyone cares to look into it.
I guess at some point I’ll start documenting which files you actually have to edit for things to take effect so people don’t spend all of their time hunting for which files actually do what they want.
Things changed in the BAC file. cancels are different, and I think some of the stuff in the effects sections in the animations part are different too. BCM i’m not sure, it’s probably different too in some ways.
We’ve got a tool that helps for changing which inputs/motions a move uses, and motion editing has already been explored enough so that I know how to change it.
editing the move motions was known a long time ago but editing the buttons is a new discovery. we can inject new moves into a character’s file now, they don’t have to take the place of other moves as they did previously.
I’m trying to do some moveswaps, but they aren’t working, game refuses to load beyond the versus screen. I’ve looked all over for a detail tutorial, but I can’t find anything.
Is it possible to edit the color select tile in the character select screen?
For example, I swapped Seth’s Color 2 skin (red) with the scale skin mod, is it possible to extract the Red color select tile and edit it to something like a black tile or whatever? Just something to make it easier to remember where my costumes are.
