Another lost newbe.... help!

OK, I downloaded the right installer and have it on an SD card. In reading the tutorial is says "For example, I have a US copy of Zelda. The inner ring of my disc reads “RVL-RZDE-0A-0 JPN” so my directories would be “/private/wii/title/RZDE/”. In this folder you would place the appropriate file according to the table. Again, in my example, I would use the file titled “rzde0.bin”. Then rename this file to “data.bin”. on SD card I only have "data.bin. Do I just rename it to "rzde2.bin" which is the right one for my copy of Zelda? And when I read the card it say "twilght hack" is that correct?

Thank fo rany help and sorry for being a pain.
