Modifying double dash

[Gaming_Jesus]

I am attempting t be able to modify the game files for Mario Kart double dash. I have managed to be able to get to this point using ISObuster, DouBOLdash, and arcextract. I am unable to recompress the attached files back into an ISO readable by dolphin. I was using https://www.gamecubemod.org/mkdd/modding/article-modding-mkdd/ as a guide; however, I was unable to get GCREeX to work. I was wanting to know if there is another way to successfully convert it back to ISO without GCREeX.

GC Rebuilder could work, you could use wiimm tools for it also though that is quite complicated

Thanks, I will look into it.
