Okay so I see what I did wrong. So I did the "svn checkout" and it allowed me to apply the patches. Only thing is that when I went to use the build it would give me an error where dir_argument_exists was not initialized(under the update.c) so I went in there and noticed that the bool dir_argument_exists = strlen(launch_dir); was commented out for some reason, fixed that, then it gave me an error saying launch_dir was not initialized. Turns out that also was commented out. After re-adding those two lines it made the loader.dol file without a problem. In customizemii I used a wad file for animal crossing that is meant for backup loaders(
https://gbatemp.net/threads/custom-...ection-for-system-menu-backup-loaders.325003/ from this thread here) and inserted the dol. The issue now is that when I open up the channel it takes me to the loading screen for nintendont but then does not load. Thanks again for all your help.
Edit: Oh and the reason why I didn't use your GetmyBannersv2 was because when I used it, inputted GAF(for animal crossing) it kept trying to download a 0kb file and henceforth failed.
