I´m not sure I shall release my debug add-on (mingw-mame-w32-QMC2-debug-add-on-20110728) or not. Maybe not because my target group should be normal QMC2 users.
Well, you could do that, but it's not really required... and thanks for the new build!
Better not. If someone ask for the debug add-on, I can offer it on another place. The DL size for this package is much bigger and need still to cleanup.
