>Hi everybody! Dio Vento here to drop off my finished difficulty hack for Pokémon Let's Go! These hacks are much less in-depth than my previous work, but should provide a solid challenge and overall improved experience as you play through Let's Go Pikachu and Let's Go Eevee.
Unlike my usual ROM hacking work, these have not been rigorously beta tested. Please point out any move or Pokémon mismatches! This is my first-ever hack done entirely in raw hex instead of through a tool like Kaphotics' PK3DS.
While my previous hacks are known for being tough as nails even by ROM hack standards, this hack targets a balance closer to Game Freak's official Black/White 2 Challenge Mode. I hope you enjoy it!
Don't worry about this setting a trend. When Gen VIII rolls around, I'm going to give it the full treatment as a sequel to my Supernova Sun and Penumbra Moon.(U+200B was here)
