Is there a significant difference in the work required? Considering how 3-button mode works, it's not like there's the potential for it to be incompatible with some games, right? I think the only reason not to have it is if you feel like you'd be making too much work for yourself.

It wouldn't be much more work to get the 3-button functions to work. The only real issue with the 3-button mode is that buttons II and I would map to buttons B and C and for traditional 2-button games, the close proximity to button A could lead to accidental pauses. I'd have to review the code when I get home and see if I can another I/O pin to make a 3 way switch happen.

The 6-button feature will be a feature of the adapter no matter which direction it takes. I put in the 6-button feature because I'm a fan of SF2CE and I think it's a technical marvel that it even runs that well. The main decision is to choose between having a 2-button or 3-button mode as the alternate. The I/O on the cpld is maxed out so I can't do a universal 2/3/6-button adapter.

That neo-geo to pc-engine adapter was my handy work. Programming for the cpld was completed the night before. I pulled an all-nighter and spent the rest of the time until 5 minutes before my flight to Milwaukee wiring and debugging the adapter. Right now, the switches toggle between 2-button and 6-button modes and are independent for each player. I am currently fielding suggestions as to how it should operate if I put it onto production. I was thinking of changing it to run in 3-button/6-button  mode for switch 1 (both players) and switch 2 will toggle between run and select for button III in 3-button mode.
