Another thing I noticed (not to nitpick but...) is the following web page link says MAMU_Icon Completion Pack 0.150 but the zip file's title says pS_Icons_149u1.zip. I'm not sure which accurately reflects the contents of the file regarding which MAME version it's synched to, whether it's v0.149u1 or v0.150... but just wanted to point that out. http://www.progettosnaps.net/mamu_icons.html
Now TO nitpick... "MAMU_" correct spelling is with a lowercase "u", like so... "MAMu_" . Nahhh, I don't have OCD . JK.
