its alreayd preprogrammed to take in the Z ones.
Actually, this isn't the case. It isn't pre-programmed to use any group of tracks. The letter Z just identifies it as one of the various fanfares used in the game (victory themes, "new trophy", "game over", etc), similar to how the letter I identifies F-Zero songs, or A identifies Mario songs. If you wanted to, you could use any of the stage BGMs as a victory theme.
For example, ROB's victory theme is Z35.brstm. Open his SlotConfig file (Slot26.dat) in a hex editor, and you get this:
53 4C 54 43 00 00 00 30 00 00 00 01 00 00 00 00
00 00 00 23 FF FF FF FF FF FF FF FF FF FF FF FF
00 00 28 5C 19 CC CC CC CC CC CC CC CC CC CC CC
The numbers in red (these start at location 0x20 - in HxD, with default settings, this is at the start of the third line) are the hex ID of ROB's victory theme (note that 0x0000285C refers to neither "Z" nor "35"). Say you want to replace it with the Mute City theme - filename I01, hex ID 0x00002778. Replace the numbers in red above with Mute City's ID:
53 4C 54 43 00 00 00 30 00 00 00 01 00 00 00 00
00 00 00 23 FF FF FF FF FF FF FF FF FF FF FF FF
00 00 27 78 19 CC CC CC CC CC CC CC CC CC CC CC
Save this as /private/wii/app/rsbe/pf/BrawlEx/SlotConfig/Slot26.dat. Load the game, play as ROB, and win. You should be greeted by the Mute City theme (or whatever else you might have as track I01).
...not that you'd actually
use Mute City as a victory theme, since it just loops endlessly
I just did that as an example, you'd want to replace I01.brstm with an actual victory theme if you planned on doing this.
(this example can apply to any character, for using any track as their victory theme - just use the appropriate base SlotConfig file, and change the hex ID to point to the desired victory theme.)
@KeiroStarr: as far as I can tell, the only way to give clones their own victory themes is to overwrite existing BRSTMs, but as above, you don't necessarily have to replace other victory themes. You could put your clone's victory theme over a stage BGM you don't particularly like, set that BGM to never load in My Music, and edit the SlotConfig so it loads the correct file instead of the original character's victory theme (in the SlotConfig file, the victory theme ID will always be those four bytes at 0x20, and the first two bytes will always be 00 00). You can't just pick a random number like Z66 that doesn't already exist, and expect it to work, since it won't have a hex ID within the game's coding pointing at it.
(I have a full list of song/SFX hex IDs that I found somewhere else on this forum or another, but I don't remember where exactly, and I don't want to just repost them without giving credit. I'll try and find the original post, and add it here later)
EDIT: Okay I got one rel ported character (Roy over Marth ported to Diddy) to work but as soon as his entry is about to play at the beginning of the battle the game freezes. I thought this was strange because I have an entry file for him and even without the entry file the game still freezes.
Is
this the port you're using? If so, all you need from there to get Roy working in BrawlEx are the files in the "For yah boy" folder. The ft_diddy.rel probably doesn't work with BrawlEx (which I suspect may be your problem - please correct me if I'm wrong!) - you'll need to use Marth's ExModule, which should have been included in the BrawlEx download. Open it with the module editor, and click on "ft_marth BX V1.1.rel". On the right, change the ID to 0x90 (or something else if that's already used). Click on the (+) to expand the menu, go to section [8], and click "Memory viewer". In the next screen that appears, double-click the highlighted section, and change 11 to 40 (or whichever ID you used for Roy). Close, and save the file as <sd>/private/wii/app/rsbe/pf/module/ft_roy.rel (don't save it over the original Marth REL!). This is working for me, at least - let me know if it still won't work for you.
Guys, you gotta help me... My clone is crashing and I don't know why! It crashes when he enters the battle. Like, Mario jumps out and it says "3"! and then it crashes. I have the filler files, and I have the correct module. HELP! (P.S. The clone is Dark Link)
Sounds like the module to me - did you change the IDs in the module itself (like I said above)?
