I found a bug in fsbext.exe (for FSB4)
That is why fsbext.exe can't works fine on FSB4
Problem is header size (my guess) And [FF FB] Blocks and must turn to [00 00 00 FF FB] (but maybe!) in Some sector's, i think so...
and the new FSB file has same .mp3 file and nothing changed or recoded... and after
rebuiling, file must be a same data then original, but some Block's has been changed
i think Sir Aluigi must fix that and also add an tag with name -4 for fsb4 and -5 for fsb5
