msx, msx2 and x68000 emulators exiting to black screen

hentai

Hello,

My system was working perfectly for these when i first created my image a few weeks ago, but lately when i try to run a game from any of those emulators, it just exits back to the menu after a black screen for a few seconds. here is my runcommand.log: (running retropie 4.5.1)

Parameters: 
Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-bluemsx/bluemsx_libretro.so --config /opt/retropie/configs/msx/retroarch.cfg "/home/pi/RetroPie/roms/msx/Alibaba and 40 Thieves (Japan).zip" --appendconfig /dev/shm/retroarch.cfg
/opt/retropie/supplementary/runcommand/runcommand.sh: line 1245:  2927 Segmentation fault      /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-bluemsx/bluemsx_libretro.so --config /opt/retropie/configs/msx/retroarch.cfg "/home/pi/RetroPie/roms/msx/Alibaba and 40 Thieves (Japan).zip" --appendconfig /dev/shm/retroarch.cfg

It's always a segmentation fault on line 1245. I've tried everything to fix this and installed all the latest updates and scoured the internet for a fix, but no go. I'm pulling my hair out. I would appreciate any assistance or insight you guys have.

This means the emulator segfaults when running a game. Do you have the required bios files ? Are the ROMs/games you're trying to run ok - i.e. not corrupted or a bad dump ?

Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

thanks for the reply mitu.

the bios files are in the correct place, and the ROMs are good - things actually load with px68k, its just too slow to be playable, and when lr-px68k used to work it worked great.

here is my system info:

Pi Model or other hardware: 3B+
Power Supply used: CanaKit 5V 2.5A Raspberry Pi 3 B+ Power Supply
RetroPie Version Used 4.5.1
Built From: Official RetroPie image
USB Devices connected: n/a
Controller used: 8bitdo SN30 Pro+
Error messages received: none, just black screen and then exit
Log found in /dev/shm/runcommand.log (if relevant): verbose log - https://pastebin.com/400hyKJd
Emulator: lr-px68k
Attachment of config files: my retroarch.cfg - https://pastebin.com/Eqm6Qg0a

Can you try changing

video_threaded = "true"

to

video_threaded = "false"

and see if it makes a difference ?

Note that this setting might slowdown the emulation for some systems. If this works to fix the core loading issues, then you should add this setting only in the respective systems' retroarch.cfg, i.e.

/opt/retropie/configs/msx/retroarch.cfg
/opt/retropie/configs/x68000/retroarch.cfg

while keeping the video_threaded="true" in the main configuration file to be applied to other systems.

Another thing you can try is to use the retroarch.cfg.rp-dist file instead and see if replacing the (long) retroarch.cfg with it would still make the bluemsx and px68k cores to crash.
