I'm playing Demon's Souls on the most recent build of RPCS3 using a PC with the specs described above. Gameplay is terrific, for the most part, however I am experiencing runtime errors at random points causing crashes. The crashes occur both in new areas and in areas I've already explored. I can't tell if this is an error caused by my PC, my settings, or RPCS3. Any help and advice is appreciated!

Also, please reference the attached screenshot - it shows a description of the error I receive when the game crashes.

Downloading 128MB of uncompressed text is obnoxious. Reupload that in a .7z, .rar or .zip file so it's something like 3mb.

Try this build: https://ci.appveyor.com/project/kd-11/rp...0.0.4-1156
It's highly experimental, but may help
