Yeah, people ran out versions before, the phenomenon we're discussing however is people thinking the old versions are the latest...

There is one point this happened before to memory, and that was when MAME32 rebranded as MAMEUI. For the longest time nobody picked up on that, and still searched for MAME32, and assumed a very old version was the current / latest version because they were so used to looking for MAME32 and thought the project just stopped when that stopped being updated. I didn't mention it though, as MAME32/MAMEUI are forks anyway..
