Tekken 4, is a patch needed?

[Stephen Wildman]

Hi ya, I was trying to backup my Tekken 4 pal the other day and it failed to boot. Out of all the games I've successfully backed up in the past, this one just wouldn't work. I have a pal PS2 V4 modded with the Messiah. Can anyone confirm if a patch is needed for Tekken 4? if there is, then I guess the Messiah can't bypass all protection out there
