btw I'm not trying to be difficult by asking for the links for these builds to be taken down.
Look at it in simple terms, while this build might be 'cool' for cab owners it's also stiflingly development of other modernized versions of AdvanceMAME. Not providing the source not only violates the license, but makes it impossible for anybody who wants to backport other drivers to leverage their work, and thus, in the long run is not a good thing for anybody.
If somebody wanted to start a project, following the license, to backport various drivers to 0.106 / AdvMAME then nobody would complain (although it wouldn't be the development teams priority to help, or accept bugs in such cases)
All I'm saying is that if you want to see this sort of thing done you should get behind people who want to do it properly, and builds like this aren't going to help such things get off the ground. I doubt I have to explain the virtues of development models where the source is available and should always be redistributed in any more detail.
