B2K... are you the unofficial, official commandline MAME "u" compiler?
And how come you didn't post the attachment MAME 0.145u7a? Is it because the time you got around to compiling, the b fix was already posted/updated?
Also, how come, in your MAME 0.145u7b compiled build, you included all those extra .exe files that normally aren't included in the official MAME binary download from mamedev.org? There are about 11 extra .exe files that are in your download:
Why did you include all those extra .exe files? And what are their purpose? I'm assuming those files have to do with compiling and source code. But why would you include them in your already compiled build download?
