[Decompilation] [th01] Difficulty-based value selection And with that, TH01 is pushed over the 50% completion mark! 🎉 This time, it's only YuugenMagan who gets no own copy. Giant RE% gains from all these calls, but let's hope I don't regret already decompiling this one for all bosses. It's not quite at the beginning of SinGyoku's, Mima's, and Elis' code segment, after all… Part of P0130, funded by Yanga.
