Have you had fun playing backups of games you legally own on physical media lately? Dumped any BIOS files from the old consoles you own?
I'm sure you have- after all, we're all about doing things legally and being above board here, aren't we? :wink:

In all honesty, I get why the official forums, subreddits, discords and what have you for different emulator projects have the anti-piracy stances they do- they don't want years of work being cease and desisted by Sony or Nintendo because of people linking to roms. I still think the pretense is funny
I played Demon's Souls on RPCS3 this past October. Even posted about it on hexbear. With the 60FPS patch it was an excellent experience, even though I think the Dark Souls games advance the design significantly enough to be better games.
I did the same thing and played it through the online private servers. Game is still a blast and introducing it to friends with functional multiplayer was great.
I tried it without that patch and it wouldn't render properly
Another user answered the problem in a response to your question, but if you're ever having issues with a game be sure to check out the RPCS3 wiki to see if there are any settings you need to change (you can right click a game and adjust per-game settings) for better performance/compatibility https://wiki.rpcs3.net/index.php?title=Main_Page
Custom configuration for that game -> GPU settings -> "Write Color Buffers" check that box.
