Yes HLE was switched off initially.
Before I switched off Fastboot, I could still access the Fpse options from the blank screen.
I tried disabling Fastboot. The sound (but not the video) of the psx logo came on for about 2 seconds and then the programme crashed. Also, after I switched off Fastboot, I could no longer access the Fpse options from the blank screen, the entire thing was just jammed for a few minutes, until I got returned to the app menu.
One other thing. When I attempt to either quit or restart, the programme freezes. Sometimes it appears to work, and sometimes it just stays stuck until I get a message asking to force the programme to close.
