Modding SF4 for PC (No DLC Unlocks!)

[Twist]

Discuss modding SF4 for PC here. :rock:

Do not discuss or post links to unlocking DLC. We’ve already seen one dude get banned - you have been warned!

Let’s get this started:

I am trying to change the music in this game so that we have the rival music in all of the stages (in VS mode and arcade etc) as I believe it is much better. Unfortunately I need help but I’ll explain how I am doing it first.

The music files are located in the directory below and they are *.csb files (never heard of this file type before).

C:\Streetfighter4\Battle\System\

After some hard work I’ve figured out which filenames relate to which piece of ingame music.

These are the rival music files (a bit like the old SF2 music),

BGM_AGL - C.VIPER
BGM_BOS - SETH
BGM_CHB - RUFUS
BGM_CLX - CHUN-LI (REMIX)
BGM_CMY - CAMMY
BGM_CNL - CHUN-LI (ORIGINAL)
BGM_GAG - RYU (SLOW REMIX)
BGM_GKI - AKUMA
BGM_GKN - GOUKEN
BGM_GUL - GUILE
BGM_JHA - ABEL
BGM_KEN - KEN
BGM_RIC - EL FUERTE
BGM_ROS - ROSE
BGM_RYU - RYU (ORIGINAL)
BGM_RYX - RYU (ANOTHER SLOW REMIX)
BGM_SGT - SAGAT
BGM_SKR - SAKURA
BGM_VEG - VEGA
BGM_ZGF - ZANGIEF

The rest of the files are the music files for VS mode and the normal stages (in my opinion most of this music is pretty bland).

In order to explain which file relates to which stage I will list them in the same order they appear on the stage select screen in VS mode - if you imagine the 3 rows of stages on this screen you’ll understand what I mean, so looking at the VS stage select screen from left to right these are the stage music files,

RANDOM BGM_USA, BGM_CHN, BGM_RUS, BGM_BRA, BGM_AFR
BGM_VIE, BGM_JPN, BGM_EUR, BGM_SCO, BGM_JPX, BGM_LAB
BGM_RVR, BGM_VCN, BGM_CNX, BGM_VNX, BGM_BRX, BGM_TRN

In order to get the rival music in the normal stages I simply renamed the files - so for example if you wanted Ken’s music on the USA stage (the drive-in stage) you would simply make a copy of the file BGM_KEN.csb and rename it to BGM_USA.csb, then overwrite the original BGM_USA.csb with the new one.

This works to some extent but unfortunately the music keeps cutting out towards the end of a fight and all you get is silence - I think it’s when the health bars get quite low. This is when the faster (more dramatic) bit of music would normally start playing to indicate the fight was close to finishing, however in the rival fights this doesn’t actually happen (the same piece of music continues playing from the start of the fight to the end). It seems as though the game still wants to start playing this faster piece of music towards the end of the fights but perhaps the rival *.csb files don’t contain it, so instead you don’t hear anything.

I can’t think of any way to fix this issue as it probably requires editing the files instead of just renaming them, and I don’t know how to do that.

Any help would be appreciated.

As a side note the files BGM_AVX_E.csb and BGM_AVX_J.csb are simply the English and Japanese versions of the title screen music (not good). Also I couldn’t find Bison’s rival music anywhere, despite hearing it when you play Bison at the rival stage of the arcade mode (it’s like a remix of Bison’s SF2 music), but that isn’t important right now.

At the moment I’m more interested in reverse engineering the Benchmark battle EMZ files. I’ve decompressed them already and they look like replay data, but I’m not 100% sure. If it is, then great, because then we could perhaps use them to create our own replays in order to measure accurate frame data, test combos/links, find infinites etc.

Right now I’m trying to figure out if the data in the header of the battle EMZ is a checksum. I hope not, because that could render this exercise useless if I can’t figure out how the checksum is generated.

I would love to be able to play the rival music in game since its more like the old school sf2 tracks, someone help this man out!

I’m more interested in the HD remix soundtrack.

Thank you for starting this thread.

I’ve managed to extract the *.csb files using this programme,

http://www.hcs64.com/files/utf_tab02.zip
(using csb_extract.exe)

They extract into *.aax files.

The rival music .csb files only contain two .aax files, but the normal stages contain three .aax files. I assume this must be because the normal stages include the faster piece of music as well.

Unfortunately I don’t know how to repack the files back into a fresh .csb file, otherwise I could do further tests.

Any help would again be appreciated.

Thanks.

If you don’t know what you are doing then you aren’t exactly modding it now, are you?

[Fermbiz]

I would love to add my own music from previous SF games. Gonna keep my eye on this thread.

Keep up the good work guys!

You might be able to do it with the CRI SDK, which you can download from their website after registering.

Anyone figured out how to get the rival music going where it wont drop? I wonder if you can just make a 3rd axx file an just zip it and rename the extention.

I would try the above but It says its a unsecure site on my browser which would be the first one ive come across…so im staying away from it.

[PimpUigi]

I want to get rid of the announcer so much.

He can say “Round x, fight” “xxx Wins” “perfect” “Ultra Combo Finish!” “Super Combo Finish!” “Time over!” and “Draw Game”

Other than that, I don’t want to hear him say anything.
Screw that “Ladies and Gentlemen, the ultimate Street Fighter!!!” obnoxious bull crap.

About the alternate costumes,

I think I found them C:\Streetfighter4\Battle\Chara\

there is RYU_01_01.col.emz to RYU_01_10.col.emz and RYU_02_01.col.emz to RYU_02_10.col.emz

Maybe if we rename the 02 one to the 01 file, we will be able to see the alternate costume? (i haven’t tried it yet)

[FallenAngel]

Let me help you out a little bit:

Not my hack
"Overwrite the files in <path>"

This only works for you, your online opponents will not see the alternate costume.

[PimpUigi]

The alternative costumes are ugly anyway.

Aren’t they???

It’s fine. The certificate just expired a few months ago. You don’t have to give them any sensitive information, and you can remove the exception when you’re done on the site. I downloaded the SDK without any problems.
