I will update the following folder for the updates (from official 0.208 to the next official release 0.209):
https://bda.retroroms.info/downloads/mame/update/
mirror: https://mega.nz/#F!aUtgzaLT!cXQiy9niYRv4Y4wv2bQt-g
Don't search/post here for stuff that is already added to 0.208 or earlier!
Note: Remember that this update folder does not contain complete sets! "Full MAME 0.208" + "update" -> rebuild -> "Full MAME 0.208rXXX"
