genesis/MD joypad 6

[dudule]

hi all,
somebody could it say to me if one to little find in the trade the equivalent of the  "sega chips" in the pad 6 ?

in the pad 3 buton it's a 74hcXXX but in the official pad 6 it's a segaXXX .

the pc engine pad and the genesis pad are similar, the pcengine pad 6 use two 74XXX, can i try to make the same one for the genesis ?

thx

sorry for my poor english.

The 6-button genny pad uses a very complicated protocol that has no single-chip solution, except for the custom Sega one.  To replicated it with off-the-shelf chips you'd need 6-8 chips working in concert.

Or a microcontroller....

are the extra three buttons really useful enough to bother?

If you consider the Genesis version of Street Fighter II to be definitive on 16-bit consoles, the six buttons are absolutely necessary. There are a couple of RPG's that use the extra buttons, but they're also perfectly playable with the three-button controller through alternate menu layouts.

There's a similar motivation for wanting to use a six button controller on a PC Engine though, since that version of Street Fighter II is arguably closer to the arcade version.

does the same apply for tg16? cos i only have two button controllers..

I don't honestly know if any PC Engine games really supported six buttons, apart from Street Fighter. I've also seen three-button PC Engine controllers, but don't know how often that third button is used. It will take a bigger otaku than I to weigh in on this topic. :)

Three button PCE pads are just two buttons with the start or select buttons (usually selectable) duplicated as a third button.  There's a full list of PCE 6-button games here on the wiki:
