Status changed to 'Confirmed' because the bug affects multiple users.

When running PCSX I cannot load ISOs or even real Playstation discs. I've tried changing between OpenGL and X11 graphics driver, as well as switching between the actual PSX BIOS and the "Simulated" BIOS that comes with PCSX. None of it makes a difference. Have ran these games on this hardware in older versions of Ubuntu and PCSX without issue.

PCSX Version: 1.9.92
OS: Ubuntu 15.10 64bit (amd64)

Terminal Output when trying to launch a game

Unsure if this should be on a separate bug report but here is my manual backtrace of PCSX.

[Brian Buchanan (nighthawk-uk)]

Here is my strace from the moment I try to open the Bin file which causes the crash.

[Edwin Lee (leeed2001)]

Same exact issue. Wiped my machine and put 15.10, now this won't run.

[Tomi Hukkalainen (tpievila)]

The Debian bug for this (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=795196) mentions a workaround:

"Upstream says that an appropriate workaround is to set Config.CPU = 1 in pcsx(r).cfg, which disables dynamic binary translation in favor of a pure interpreter."

[Brian Buchanan (nighthawk-uk)]

The workaround mentioned worked for me.

I edited '~/.pcsx/pcsx.cfg' and changed 'Cpu = 0' to 'Cpu = 1'
Now my games run again.

This solution has resolved my issue.
My games also running again.

This bug was fixed in the package pcsxr - 1.9.94-2

---------------
pcsxr (1.9.94-2) unstable; urgency=medium

  * Add patch to fix FTBFS on non-Linux architectures.
  * Add patch to remove use of __DATE__ to make the build reproducible.

[Brandon Spradlin (deep-thought)]

can you put the full path to the .cfg? i cant seem to find it anywhere.

[Brian Buchanan (kehoroblade)]

There should be a hidden folder called .pcsx in your home folder, the cfg file is in there.

/home/[USERNAME]/.pcsx

[Brandon Spradlin (deep-thought)]

ctrl+H is a beautiful thing. thanks, fixed my issue as well.
