Not only that, but Capcom seems to be adding this Enigma Protector bullshit to their back catalog as well, if this Steam forum discussion is to be believed. Bet this borks the games on Linux and Steam Deck now.
Once again I'm astounded by the stupidity of these publishers. These games are already cracked, so why would they retroactively make the paid, legal experience worse on their finished products? Can we make this practice of retroactively making a product worse illegal?
I've said this elsewhere, but I think the reason is because they felt embarrassed by that one Street Fighter tournament where the hosts had a nude Chun Li mod on. They're overreacting and putting DRM in place to stop mods from working in general so that can't happen again.
Link to a better explanation by FluffyQuack, Capcom has added this drm to games for a long time. Not really affecting mods in general, don't know about the linux/steam deck compatibility.
