He's using brawlscape

ah right, wel you'll have to reduce the amount of colours, do you use GIMP?

Really? Try switching ALL image formats to CMPR (until the file size is not above the limit)

EDIT: I'll try and reduce the file size myself if you want.

Mines 3592 KB (3.5 MB)
1 megabyte (MB) is 1024 kilobytes (KB)

I'd say porting wouldn't be a bad idea regardless of the limit, better chance of it working as well.

i reccomend exporting ikes name in brawlbox then replacing olimars with it shouldnt freeze then

He's saying it freezes when he replaces it, he's not asking for how to replace it.

Yeah, I had a lot of problems with my scrubbed iso :/

Use the sc_selcharacter.pac, it's a lot easier and I don't think it has a limit. Export your sc_selcharacter file from the common5.pac and place it in the menu2 folder. (I use usb loader GX as well)

Alright, so your using gecko.

Which usb loader? (Size limit?)

And because your using the common5.pac instead of the original sc_selcharacter.pac in the menu2 folder i'm presuming your using riivolution, correct? (Brawlscape is quite an interesting tool but i'd reccomend you use brawlbox v6.3d)

Is everything in the correct place? (and what donaldthescotishtwin sorta said, is everything the right size?)

Yeah, when posting at least follow the rules

All I did was download the stage, place the .rel files in my modules folder, put the stage files in my Stage folder, and make the selection icons for each stage!

The selection icons appear, but when I press them, the game won't freeze, but it just loads continuously!

Then what i'm saying is correct

What stage modifications are you using? I'll try and fix them

What are these custom stages, are they stages added from the stage expansion code or not?

If they are it depends on which stage track the stage is using. The stage will also have to share the the soundtrack with the stage the track was made for.

Ex. Battlefield---> Battlefield Soundtrack <---Icicle Pyramid

Brawl's music is in the strm folder in the sound folder. Brawl vault has all kinds of music that can replace the songs. The music files can be found here

Wiiflow, usbloader, and gecko part is nothing to be concerned about. Have you modifyed your common3.pac file? (found in the system folder)

After

It freezes! Finally, i put the partition back in  the iso, but it said "partition too big" so i deleted the 2 dummy files. When the ISO comes out, the games size was like 90MB less than the original ISO, and the Wii freezes at the begining of the game (In the strap screen (how i Mod)). What was? The dummy files or the strap screen?

Too large hmmm? You better not be using v1.2 of partition builder 

It's partition 1 you need, partition 0 does not have any brawl data so that's probably why your getting that error. Also don't double post 

Where does it freeze too?
