.rel coding help

[Chosen Hero]

Just a quick question here, I have .rel files for the Lucina PSA 1.5 King Dedede and under the READ ME, it says I need to add in codes to something but I don't know where to do that at. Does anyone know where the codes must be typed in at. If someone could tell me a step by step process of where to type the codes I would appreciate it.

Use Brawlbox v0.70 or gct edit and open up you RSB?01.gct file. Now just put your codes in it and save.

well I tried to save the codes in the RSBE01.gct using BrawlBox v0.71, opened code manager and typed in the codes, but when I clicked on File -> save it would not save over my old .gct file (the modified date did not change) is that how it is suppose to be?

If you are saving it to the correct place, try saving elsewhere then transferring to the sd card.

I probably should have noted that I am using Project M 3.02, not regular Brawl so would there be a problem with that? If not, then I would like to ask this, when loaded, the RSBE01 is said to be "unrecognized Code", is that normal? and when I type in the new code it is completely parsed (I'm assuming it was typed okay) so when saving do I click remember code then save as? Furthermore, do I have to click the "Save GCT with" so the check mark is gone or something? Also, SoundBank Mod Codes go in the RSBE01 also?
Thanks for the time and info and sorry if I'm being a little noobish
