The cause of this bug might be related to NelsonPJ's a few posts down but I'm making a separate post just in case.
I'm still working with MAME 0.129 as I had taken a break from the hobby for the last year or so.
Mala 162 can scan my MAME roms folder and will create the gamelist without problems.
However, I actually have my roms set up per SGT's method to integrate Daphne and Makaron into the MAME gamelist. I have MaLa setup to look only for roms found in folders.
When I add my OtherEmu folder to the MaLa rom path I run into two scenarios:
1. Not adding information for the new roms to mame.xml: In this case, MaLa will simply ignore the dummy roms found in the OtherEmu folder if they don't have entries in the mame.xml file. This works as it is supposed to.
2. When I add entries to the mame.xml for the non-MAME roms, mala crashes while creating the game list.
This has me stumped because on the previous beta (1.0.5xxx) it works without issue so I know my mame.xml entries are not bad.
Also, I made sure not to have duplicate roms in the MAME and OtherEmu folders.
Is this a known bug with the latest beta?
