I wasn’t expecting quite such a positive response from the initial ‘Ultimate MAME’ post, but it seems like a decent number of people really like the single binary concept.

Anyway, there were a couple of issues with the MESS 0.144 source on which it was based, these have since been resolved, as well as several other changes made which may be of benefit to this build. In the 0.144 release things like c64 would just crash due to aforementioned MESS bugs, and the code for some MESS drivers would end up being compiled differently to a standard MESS binary due to it being hidden behind #ifdef MESS defines in the source. Micko has done some work on removing those cases, although he did manage to introduce some additional conflicts in the process which I’ve fixed and submitted a patch for.

Anyhow, what this means is that I’ve done a quick update of the build against 2 newer GIT revisions (MAME and MESS which should fix this handful of issues.
