First and foremost consider this:

Only RetroArch bugs should be filed here. Not core bugs or game bugs This is not a forum or a help section, this is strictly developer oriented

Description

[Description of the bug] When using vulkan video drivers in retroarch, mednafen_psx gets stuck at Playstation boot screen and displays Bad sector error(tried mednafen_psx and mednafen_psx_hw).

Expected behavior

[What you expected to happen] Game should load or run.

Actual behavior

with retroarch using vulkan drivers, when you load a game using mednafen_psx software or hw core, it just gets stuck at PS boot screen with bad sector notice.

Steps to reproduce the bug

run retroarch select vulkan driver close retroarch run retroarch choose a psx game select mednafen psx core / mednafen psx hw core Bad sector? 2 Bisect Results

[Try to bisect and tell us when this started happening]

-using the same steps above to reproduce bug but set retroarch to use opengl drivers does not cause bad sector issue with mednafen_psx or mednafen_psx_hw. -cd image are redump verified(cue is is renamed for easier loading in retroarch-avoid that name scrolling with long text lines) -there has been talks in forums and other sources of such issue when using vulkan in retroarch. i even offered a HAVE_CDROM_NEW compiled mednafan_psx core and they still it still displays bad sector. that time i thought it was just a bad translation game, since i do not a way to test vulkan yet. -tested only in ubuntu since it can load vulkan drivers for my gpu, my windows box do not have vulkan to test and compare.

Did you try to enable "CD Image Cache"? I think I suffered from the same problem some weeks ago and it disappeared by setting this to "on".

Yeah, Twinaphex has been suffering from this for a long time but hasn't been able to figure out the cause. It only happens with X11, as well. Wayland doesn't have it.

Which game? Because this is pretty normal on misapplied translations or even in some few badly made translations (that then can get fixed with a tool like error_recalc )

Just now i had various 'bad sector' errors in Akumajou Dracula X (symphony of the night japan) translation. It was because the readme had 'apply this to the first edition' but redump had the brilliant idea of naming the 'first edition' version 1.2. I thought it was just broken on the emulator when i tried error_recalc on top of the translated track and it still gave the blackscreen, minus the bad sector warnings on standalone mednafen, but no, it was actually the version.
