I'm not sure you really read what I've written earlier... QMC2 doesn't read or write the ini's, though you can export to / import from them smile. It's all stored in qmc2.ini. The readconfig option will decide if MAME reads the ini's... it has nothing to do with QMC2.

Regarding the 'save' icons, I'm aware and that has been fixed meanwhile (though the actual bug was not only a GUI thing). This has been discussed in the 0.41 release thread.
