I am sure it's not my own case; we have different characters over one PSA, but when we select one, we see the name of the "original" character, for example: I have Meiling over Ryu, but when I select her on the Character selection screen it shows the name of "Ryu" due to the other Ryu recolor slots.
Well, I found a way to change that.
First than anything, we need to "clean" all the CSS names, this means, deleting them all to replace each one for each texture we have.
Use this black image with these exact proportions
right click and "save image as" ----->

Now open sc_selcharacter_en (it's inside common5.pac for riivolution users) with brawlbox and spread miscdata30, then go to "textures" and slide down until you can see the CSS names and replace each one with the provided picture I gave you.
Once when you did it, the CSS names are clean and no names will show in brawl at the CSS, so go to char_bust_tex_lz77 and spread it to replace each CSP with a new CSP with a name placed over it.
For example:This is Kirby's CSP how would show in selection screen now
so we replace it with one with a name on it
Now do the same with each texture.
Here have my personal Kirby CSP's
That's all about this, thank you for reading, I hope it's useful for you.
