You can use the category tags in the DLC store to see which packs have generator parts. Just make sure you specify for MV or MZ (I don't know which you use, you didn't set it in your profile) as the poses are different.
Also read carefully, because some will come with generator parts for the map sprites but not side-view battlers (the same is true for generator parts you may find in threads on the forums).
Finds notes for an old side project... Oh, that's right, the two tracks that sounded really cool and gave inspiration for the big bad in that game... Spends day working on cutscene from old notes, looks okay, now lets slot in the first track... um... I did have those tracks??? It was a year or so ago but I did buy them didn't I?
Well, I'm quickly recovering from Covid, but I'm still broke and injured lol. I miss working on my game! I think I've figured out a lore-friendly way to do a tutorial section separate from the main gameplay, but it'll take some scripting know-how. Which I don't have. And can't afford.
