Remake sucks, avoid the HD Collection entirely.
SH1: Duckstation standalone, disable dithering (I couldn’t find the official compatibility list/configs but it shouldn’t be hard to find some from the community)
All PS2 SH games: PCXS2 Standalone
SH2: Set the controls to 3D mode (might be in other games, I can’t remember)
configs
SH3: Avoid hard puzzle mode for your first playthrough
configs
SH4: Avoid hard mode for your first playthrough, don’t listen to anyone who bitches about this one
configs
Remember combat isn’t the focus of these games.
Easy difficulty is a valid way to experience the story and atmosphere if you hate the controls.
