We have a string editor which is functioning and knows the whole file format !
I've reworked 99.99% of the format and the 0.01% isn't used right now !
Know that EA have made big mistakes in the format and I know why this is happening, but that's EA case to resolve their problems !
I'll do some tests and will post it here after I released the editor to "public" state ! I think, I'll release it tonight !
The editor is free for personal use, commercial use have to license the software !
