It was implemented in the last update. It has been renamed as DISCRETE_74LS624 and the old code removed. A 629 is just two 624s. Mario Bros has been updated to use it.
The DISCRETE_XTIME_xxx logic modules just allow for anti-aliased logic, creating a better waveform. The dkongjr sound in 140u1 should sound subtly different then 140. The final filter removes a lot of the aliasing noise that was there before the new DISCRETE_XTIME_xxx logic modules. But I know it was there and could see it when doing a waveform analysis. Now the harmonics are gone.

Do not p-mail me for help compiling my updates, ask on the board.
Do not request sound for your favorite game. I work on whatever, when I get around to it.
If you have schematics for discrete sound games not easily found on the net, I would be interested.
