Convert PAL ISOs to NTSC?

[NitroHedgehog]

Long time no see and sorry if it ain't the right place to post this...

There was a small tutorial claiming it is possible to change a Gamecube ISO's region with a Hex Editor. They said to go to offset 0x45B of the ISO with an hex editor and look for the digit. 01 is NTSC and 02 is PAL. However, whenever I change a PAL ISO (ripped by cousins in Switzerland, NOT downloaded) to NTSC, the ISO gets corrupted and unplayable...

Another thing I tried is this: I have ripped a NTSC ISO from one of my games (Zelda: The Wind Waker) in hopes to make a full translation from English to "xyz" language on the PAL ISO, owned by my cousins in Europe, as some of my family and friends aren't speaking English yet... However, the game is not just about text to translate, but also graphics editing. Every graphic can be found in the NTSC ISO.... or so I thought. For example, the graphic files for "New Game" (file selection screen) and "Outset Island" (when you start a new game) is absent from the NTSC ISO, but present in the PAL one in all possible languages. As a result, the NTSC version cannot be translated the way I tried to do it... is there a better alternative to convert PAL GC ISOs to NTSC? Many thanks.

I'm afraid you're looking forward to overcomplexify what you really need to do.

What is your specific setup that requires you to do more than just use the native Pal ISO of a said game that supports 60Hz output anyway?
