Dance Dance 4th mix protection fix ?

[rs1959]

I am a total newbie at this, so please be patient with me. I have the DDR 4th mix game, which I can play ok on my ###ne using a 'boot disc', and then entering a series of codes. Its a pain to enter the codes every time. I read the discussion here about applying patches, and I follow it ok. But, for what I am trying to do, I assume I need a "protection fix" a opposed to a "pal" converter (.p4u file) Is that right ? For the 'ddr 4th mix' game, there only seems to be a .p4u file, and no protection fix file. Anything I can do - any way for me to play that specific game without entering codes every time. Thanks much for any help or pointers.
