Also, for technical details, the format of the ROM files for MAME 0.72. They might require .zip files in specific directories. The structure of the ROM set for that version. Also, maybe some quirks or issues users should be aware of when using MAME 0.72, since it's an older version. For example, some games might not work correctly, or certain features of the emulator might not be present.

Wait, some users might consider using older MAME versions for specific reasons. But there could be legal issues with using older versions, as Capcom and other companies cracked down on ROM distribution. So I should mention the legal note.

In the user experience section, talk about the interface, controls, and how it compares to newer versions. Maybe the interface is more command-line based or has a different UI than current versions which support more features.

Additionally, alternatives to MAME 0.72. Perhaps newer versions of MAME (like the current 0.217 or so) have better support for more games and improvements in accuracy and features. So suggesting users consider updated versions if possible, unless they need specific compatibility for a particular ROM.

Now, focusing on MAME 0.72. I should probably explain the significance of this version. Maybe mention when it was released. Wait, MAME's release history is a bit long. 0.72 would be older, like 2000s era? Let me confirm. MAME 0.78 was the first to work on Windows 98 and had the first major UI updates. But 0.72 would be a few years before that. Maybe around 1998? I need to check that date, but for the purpose of this feature, maybe approximate.
