After comparing Dreamcast version with all enhancements RetroTink 4K can offer with RetroArch/SwanStation, I must admit that playing on a physical console doesn’t worth it at all.
While colors might be attributed to how my capture card processes HDR signal, it’s undeniable that models and textures rendered in x5 resolution look significantly better.
The most important parameter to get this quality of picture is PGXP CPU Mode. It is supposed to be slow, but very accurate way to represent 3D models. Something that PSX was never good at.
Interestingly enough, Dreamcast has some new textures, for some reason (notice the plaque has moved a bit):
Back to the game, it is interesting how you meet Carlos at different points in the game, depending on which location you visit first. On Dreamcast, I’ve met him in the restaurant. But on my PSX playthrough, I wanted to avoid Nemesis and went to the newsroom first. And here Carlos was waiting for me again, with a different cutscene.
Speaking of cutscenes, the game has QTE events, even before Shenmue! Sometimes when Nemesis appears, you are given a choice, between fighting, running away or hiding.
