At the moment it looks like only nes.xml includes dipswitch tags from the DTD. They don't seem to show up in the UI as far as I can tell. Are they even exposed via the UI or command line? I'm guessing no, since nwc90 has working dips but uses the ioport stuff.

TL;DR: those dispwitch don't do anything

Originally, I added them so to document chinese bootlegs DIPs with alt options, that often are the only difference between boards.
In the end, emulation-wise, it was easier to add them as ioport, and the XML documentation is mostly there for legacy reasons

Yeah, I noticed the tag when adding mapper code for a...Chinese bootleg with DIPs (Dr Mario II). Sounds like what it looked liked, but then again I'm not too familiar with most of the MAME code base. Thank you for the info.
