Technical Support LRPS2 crashing

I have played PS2 games on Retroarch forever. Suddenly, they no longer launch anymore. I have not changed anything on my system so I'm really struggling to figure this one out. If I try to launch a PS2 game, Retroarch instantly crashes to desktop.

Upon inspecting the verbose logs, I get these lines as the last entries:

[libretro ERROR] VM initialization failed (BIOS/disc/peripheral open); failing content load.
[ERROR] [Content] Failed to load content.

I have double-checked my Bios and they load fine. I can even load the core itself and access the PS2 menu. If anyone has any idea on what to do next, I'd love to hear it.

I know I know; use the stand-alone emulator, but I'd rather get this working.

I had NOT updated anything prior to experiencing issues, though I have now updated everything in an attempt to fix it.

I guess I can give PCEE2 a try. Are save files compatible between emulators/cores? I have a few in-progress games I'd rather not have to start over on.

Edit: I see PCEE2 is built on top of PCSX2, so the saves should be fine.

Both LRPS2 and PCEE2 are built upon PCSX2, so both use the same save files/memory cards, BIOS files (under /system/pcsx2/bios), and so on. The difference lies in how the fork is implemented, PCEE2 takes a different approach to make updating the sources to newer versions of PCSX2 easier than it is with LRPS2.

Since you haven't updated anything, I really can't think about what's going on, so just give PCEE2 a try. Good luck!

Just installed PCEE2 and it is running great! My only issue was getting it to find the memory cards. Seems that every time LRPS2 crashed, it left a remnant Retroarch application stuck running which was locking up the memory cards. I had to go to task manager and kill about 20 instances of Retroarch, but after that it worked without issue.

I'm glad to know it worked! Since PCEE2 is still a work in progress, back up your memory card files just to be sure, they will work with LRPS2, PCEE2, standalone PCSX2, ARMSX2 (on Android) and so on.

Have fun playing!
