Chad Gray's VMMenu - New Version (Ver 1.2 - 03/15/2011)
This is an alternative to the Vector Menu driver written by Ian Boffin, that was included with the ZVG. It picks up where Ian's left off. (Chad worked with Ian, and uses his graphics, and assuredly some of his insights.)
New in this version is:
support for old versions of mame lacking the zvg_menu switch,
smarter navigation mode option,
keyboard led support,
and various other tweaks.
With rotation added previously and customizable controls plus spinner support, this should be usable in Tempest cabs.
