- When analog info "hangs" does it show a popup dialog with nothing in it, or is there no dialog whatsoever?
The popup appears with the blue "Analog Info" box and a line... but nothing under it. It just sits there doing nothing. I ran the same thing on the JXD 7800B and it works, the dialog pops up with all sorts of info.
- Are you able to actually get analog control working with the current version of the app? i.e. can you get mario to walk or does he always run?
On the 7300 Mario RUNS everywhere once you setup the controls. On the 7800 it works perfectly right out of the box. Mario walks and runs

Speaking of the JXD 7800B... I was going to send all the Controller Diagnostics but I realized that every key/stick is set to "ADC keytouch" and is simple different X&Y axis values. The only exception are the four shoulder buttons... they are not setup to do anything out of the box.
I think the biggest difference is that on the 7300 the default N64 emu is not Mupen64, but on the 7800 it is the default emu... so all of the settings are pre-done and work.
