Can we make a start on fixing MAME/MESS entries?

First off, enormously grateful to those that keep the MAME metadata updated, but we desperately need something like a "MESS" platform for the database so we can add metadata that doesnt fall under the arcade description. I understand each computer will have its own entry, but I'm referring to things like LCD handhelds, system devices, chess machines, and all the esoterica. This will help clear up a LOT of incorrect entries. We're tens of thousands of games in for MAME now, and it's only going to get worse. I'm happy to do my part, but I can't do anything without a proper platform.

To clear up any confusion, the following picture; using Ms. Pac-Man as an example; shows the same id (#15079) being automatically attributed during import to at least four games. Only one of which is the actual arcade game. The other three in the screenshot are handhelds and a plug&play game.

What I propose is to either add a MESS platform to the launchbox database so we can add the games that don't fall into the arcade category, and are slipping through the cracks, or Handheld, Plug & Play, Chess Machine etc platforms. Something, anything to avoid repeated errors cropping up for same name games.

Does skipping non-arcade games when importing no longer fix the issue?

If you don't want the games in your collection sure, but the database still lists them incorrectly, so the problem persists. Whether you import a single game or as part of a set you'd expect the metadata to have the correct information for it.
