This happens to me as well and I have to power off to recover. I don’t know why MAME is hard crashing and hanging the entire system, but its super annoying… I have games that do work so it isn’t everything.
This behavior was there in 5.24 and 5.25 as well.
Check your romset. lr-mame does fail nicely when a file is missing.
Remember. We don’t support MESS.
I tried everything with different romsets but problem persists. For now I use MAME 0.139, but that would be good to have latest version with all the bugfixes from last 10 years working. Maybe lr-mame can be debugged, so I could post here some logs?
Are you using your 0.139 romset with 0.220?
Of course not. I tried full non-merged 0.220 romset and there are problems in batocera. Tried many other rom sets I found in internet but without success. As I mentioned before - error log from lr-mame would help a lot but I failed to enable it.
I had no problem with the games I tried. Check /userdata/system/logs/es_launch_stderr.log.
Thanks for the hint. I suspect merged/non merged status as a cause of the problem.
I used a split set. Not aware about problems with non-merged sets.
I raised this point to poke a few days ago, tested myself with a non_merged set and I have no issue on PC.
Did you change the emulator/core used for the mame system in Games Configuration menu in EmulationStation ?
Yes, all the configuration changes were correct, I checked it. Just have to spend a day or two to figure out where the problem lies as it is the last issue I have with my Batocera.
beastieboy Could you list one or two roms?
Some other users reported the same problem, but as I said we can’t reproduce it on our side
