I like common ground setups but My next project is definitly going to use a WIRED controller, dealing with battery voltages was a total pain with the Saturn adapter, mostly because I'm horrible with designing for efficiency.
Also I'm considering this for the Achievement Machine, and many of the uses involve letting it run for hours/days at a time so a hard wired device makes a whole lot more sense.
Also I'm interested in leaving in the original shell so the controller can still be used normally, I'd like to get the bottom half of a wireless controller so I can gut the battery bay and use that to house my AVR/other components to make it look as factory as possible.
There are a few other project I might tackle but this is the one I have in mind right now.
a common line setup is so awesome for custom modifications, it literally cuts my part count by over 80% I might even be able to get this done with a single chip if I'm crafty.
Interesting enough this hack was featured on hack-a-day today: http://www.acidmods....p?topic=17385.0
they use the new style controllers to build PIC controlled macros
in any case they also produced the model numbers of the controllers they used
I have no idea if these are the same as the older types or not, but at least it's something.
