Unable to auto boot games in rpcs3..

The Quickstart Guide specifically indicate that you shouldn't place disc games there.

I just ran the command with the same game, and it launched the emulator and automatically booted the game

D:\RPCS3\bin>rpcs3.exe "E:\Games\PS3\BLES00932 - Demon's Souls\PS3_GAME\USRDIR\EBOOT.BIN"

Maybe you have the "Automatically start games after boot" setting disabled? It's enabled by default though.
