I recall seeing a couple 1970s era Japanese region flyers like that. It would be flyers that are currently not on TAFA at this time.
As for other similar games, Diamond Derby is supported, but not working yet.
Steeplechase would fill out the 1970s era horse racing, if it can ever be supported (non-cpu game). It appears that game runs from a single board rather than the standard multiple pcb units that were used for many non-cpu games.
