How to change region for Melee (and other GC games)

This will make your Wii read the ISO as a PAL-ISO natively thus allowing you to get colour on your TV even if it doesn't support NTSC. If you already have a savefile for PAL that the ISO could read from, delete it or make a copy somewhere else. If you wish to transfer your NTSC savefile, follow step 5. The process can also be reversed. If the first line doesn't say "GALE" (47 41 4C 45 30 31) (e.g. the PAL netplay community build has the gamecode PALE) or you want to change it for a different game, just change the E to a P.

1. Download a hex editor if you don't have one (for example HxD, https://mh-nexus.de/en/downloads.php?product=HxD)
2. Open your ISO in it
3. Depending on your hex editor, this step can be done in different ways:
	Change the first line from [47 41 4C 45 30 31] to [47 41 4C 50 30 31];
	Change the ASCII "GALE" to "GALP";
	Change Offset 00000003 from 45 to 50.
4. Save your ISO
5. If you wish to convert a savefile as well, do the same to that.*

*Note that I have only tested savefile compatibility for Melee and while other games probably works, their savefiles can potentially break.

VERY IMPORTANT: When editing bytes, make absolutely sure that you don't change the length of the file. You must only edit the values of existing bytes, NEVER erase or add more or it will ruin your file. Highlight and replace, don't use delete or backspace.

Other region flags:
	E - USA/NTSC
	J - JAPAN/NTSC

You could also change the first letter to anything EXCEPT a "D" (44) or a "U" (55) and the second and third letter to 0-9 or A-Z if you want to make a unique header for a specific version. For example GALP for your standard vanilla ISO, AALP for 20XX with PAL signal, BALP for 20XX:TE, CALP for Melee Minus etc.
