>If not, I'm sure Robert will have them in the next HBMAME for the time being.
Robert already has them added for the next build (0245.12). He's Jonny on the spot with this stuff. I also sent both complete sets to the dumping union with links to board information and screenshots but haven't heard anything since. Since these are "official" boots and not some personal hacks I'm hoping/assuming they will get added to MAME at some point but at least they are in HBMAME for now.
