if the ROM is THAT old, chances are it has a ton of bugs! they dont issue ROM releases unless there are new features which cant be put into software, or there are some nasty bugs, or software/driver patches that eventually got moved into ROM.
I would rip a good copy and reburn the one you have. I have a willem programmer which will burn just about any ROM, but I lost my UV eraser long ago so I gotta get another one, but I havent reburned a ROM in ages so I never replaced it.
