Seems like a pretty reasonable request to me, surely there is a test point that could be used for this?honestly I'd be happy if the multi just includes a solder point that goes high or low depending on which frequency the game requires (heck even controlled by the config file for the game as opposed to anything fancier. Then those who care can install the DFO and wire it up themselves.
Maybe it is something that can be added in a firmware update later if not on release
