MAME's V-Tech V.Smile driver has been working nearly perfectly for a couple of releases now, but there have been some games that require custom controllers that have been a bit elusive to reverse-engineer.
Thanks to the efforts of MAME contributor "bmx" to both acquire a dance mat, and hook it up to his logic analyzer so that we could figure out what was being sent to the base console, I was able to implement a working emulation of the dance mat controller for this particular series of games.
As a nod to bmx, I chose the French localization of the game, but the German and Spanish localizations of the game work just as well. In principle, the regional variants of Jam Gym which have yet to be acquired - US, UK, and Netherlands - should work just as well once they have been acquired and dumped.
If there is anyone in possession of the above regional variants and is willing to send them off for preservation, please reach out to me.
