Oh, it’s not my git, I’m just using the GT6U github repo since it’s searchable, since I haven’t really understood how I’m supposed or if I even can search gregit for GT6 stuff. I just searched by code for any instance of “extra simple”. I’m afraid I’m not particularly knowledgeable of the subject, but ExS is from MD.java, along with a long list of mod IDs which I assume are shortened and used as a reference when needed

It is also found in CS.java here (at the bottom) while looking for extra simple.

do the ExtraSimple String IDs match the ExtraUtils ones, so I can exchange them if needed when asking for Recipes?
I have no clue, honestly. I have a poor knowledge of the codebase and I was led to believe from looking at the snip from WD.java and some vague recollections of discussions a while ago with one of the extrasimple players (to say it’s an extremely niche mod would be an understatement) that portal support had been added to the mod after a request. Extra Simple’s mod ID is “ExtraSimple”. If needed I can provide a link to the latest version of the mod itself.
