How to change in game battle name for custom characters?

[jae]

I have several custom characters replacing other characters (Goku over Pit, Ryu over Jigglypuff, etc.). I changed their character select name and pic, but I am having a hard time changing the in battle name (ie when I play as Goku his in battle name is still pit.). I edit the info_en.pac and place it in info2 folder and it doesn't work.

Any help is appreciated

change the info_en.pac name to: info.pac

EDIT: I guess I saved it wrong. It works now thanks!
