Hell yeah!
Thanks for this news.
Sadly the older ones with the bankrupted company are under oblivion, and the
alive ones are exploited ad eternam from companies like Activision.
That's a good reason to make the ROMs free. We must demand it.
The ROMs are non-free, but considering this a legacy gaming preservation
project for historical reasons, I could make an exception (and some old games
have its company long defunct, so getting the source code is literally
impossible).
Took them long enough, but here you go: http://mamedev.org/?p=422
