After installing Mame 0.217, all qmc2 software lists are empty "no data available". If I reinstall 0.216, all is well. I've got to wonder if this might be the cause:
• Enhanced -listxml, -listsoftware, -getsoflist and -romident to support software lists enabled by slot card devices. [Vas Crabb]
Perhaps one of the changes confounds qmc2's lexer?
Anyway, before I report this as a qmc2 bug, I was wondering if anyone else has the same problem.
