SofaRun v2.0 teasers
Very nice 
.
As for the button combination, I wonder would this not interfere with action games where you would often press A and B at the same time (e.g. Aleste), or games where the A+B button combination has some function (e.g. it brings up the menu in Xak)?
Is that a Microsoft Sidewinder gamepad you're using? That works with a JoyMega adapter?
Yes, that's a Sidewinder. That's one of my favorite game pad, I find it accurate and comfortable at the same time.
It's not JoyMega modified, I just cut the internal connections and rewired everything to MSX using a DB9 plug. It's quite easy to do as there are free soldering locations for each button in the internal PCB. I also wired the green led to MSX +5V to have it lighten when MSX is powered on.
I wire the 3 bottom buttons (A,B and C) this way:
A -> MSX button 2
B -> MSX button 1
C -> MSX button 2
This way, you can always have "shoot" on the left and "jump" on the right, even with games that are inverting that (that's something I really don't like, too much body-memory I guess 
)
I think it would be quite possible to fit a megadrive PCB controller card inside this model (you can get one from the cheap chinese megadrive pads available on the net), along with a small JoyMega converter. I'll maybe try it.
