Price with a single pad 6,980 yen (about $60) with two pads coming in at 8,980 yen (about $80). It’s a “full sized 6 button pad” but not sure if that means the smaller JPN model or the larger NTSC/PAL.
M2 doing emulation means Sega is trying to make this a decent product and I hope it’s a big hit for them but I wonder if the more mainstream market is burned by their previous attempts.
It’s quite interesting. To add extra buttons to the simple Switch of the SG1000/Mark III/Master System pads (which simply grounded lines) they added a multiplexer. The signals are backward/forward compatible for the cardinals and B/C (I/II on SG/M3/MS), but use a combo two signals multiplexed to run Start and A.
Then for the six button pad they added another switcher, but this one is controlled by a signal from the console.
It’s quite funny how, like the console tech (MD is a Mark III + extras which is a SG1000 + extras), the controller tech was layered on top of the previous tech.
