Can confirm this works on Sun and Moon as well (I knew it would, but just confirming that it in fact does). the garc for SuMo is located at a/1/3/7. Just replace all instances of that code once again with 0's (including the "E0 01 07" bit). If you're doing a Ctrl + F or Search and Replace, I would start off with "C0" rather than the bunch of 00 00's. There are only 14 iterations of that code, which is very very unusual because there were 29 instances in ORAS and a different amount in BW2. So I guess the moral of the story is that it's all encrypted, and there is no rhyme or reason to the "number of banned pokemon" to the number of banned code reptitions. I've made a video demonstration on my channel which I will not share in this post, but here is some additional photographic proof:
Next step: Edit number of pokemon and pokemon level! lol jk... Also for what it's worth, the file size in ORAS is 33 kb whereas for SuMo it's 29 kb (and it's 8 kb in Gen 5 for comparison even though i know NDS is different). I think that's rather interesting, and sheds some light into the structure of the ways these garcs are organized.
Another interesting tidbit: Neither of these banlist garc locations were figured out during the initial decryption phase of R&D. In ORAS, the garc was labeled
a\1\7\0 - 53 * 604 bytes Battle Video Info Markup Template
from this pastebin uploaded by Kaphotics and it was labeled
a\1\3\7 - com_seasand02 02_beachslope
from this GBATemp repost by BelmontSlayer. I would be interested to know if a/1/7/0 does still contain a Battle Video Template, because I wasn't sure if each garc did only one specific thing or if they could do multiple things. But anyway, thank you so much Kaphotics for your help and ABZB for all your contributions! I know a lot of people have been asking about this and I'm glad the community can finally put this issue to rest.
BTW, I still don't have it for X and Y and I'm not sure if anyone wants it for X/Y. I won't waste time finding the garc for XY unless someone wants me to (or you can just do it yourself )
