Hey, that is AWESOME!
Dogga (my son) LOVES that idea of being able to save his game.

4 days eh!
You’re obviously quite a bit more intelligent than an old-fart mechanic & a 12 year old boy. Funny, I thought 12 year old boys knew EVERYTHING! lol.

We’ve had ours a week now & all we managed to get sorted was grafting an old car DVD monitor to the composite out & getting most (SUPER NINTENDO doesn’t play nice) emulators to display the games nicely on that particular screen.

To be honest, grafting the screen to the Raspberry Pi was a tad more involved than we gave it credit for. The pin-outs on the jacks were completely different so we had to decipher those, then jury-rig them together, then work out how to get it to display nicely. (again, we haven’t quite worked out how to get SUPER NINTENDO to display nicely yet but others are nice).

But now it’s done, we’re gonna try & get the raspberry pi moulded inside the rear casing of the screen & just hang a couple of USB ports out the side of it as well.

That way, he’ll have a portable RetroPie that he can play in the car & caravan.
AWESOME!

Thanks again Peter,
we REALLY appreciate your help mate.

Hey Peter,
you are my son’s newest HERO!

That works a treat!
Thank you so much for making it simple to understand.
We would never have gotten this far without straight-forward instructions.

We’ll take your advice about the joypads you suggest, as he really does want to make it a 2 player machine.

One other thing if you don’t mind.
Is it possible to have the screen ROTATE 180deg to face PLAYER 2 just like the old “cocktail” gaming tables?

Thanks again,
greatly appreciated

Oh sorry, my bad, I didn’t have both joysticks plugged in.

I ran that command & it took me through a setup procedure that has the following buttons / movements to map:

B button (down)
Y button (left)
Select button
Start button
Up D-pad
Down D-pad
Left D-pad
Right D-pad
A button (right)
X button (top)
L button (shoulder)
R button (shoulder)
L2 button (trigger)
R2 button (trigger)
L3 button (thumb)
R3 button (thumb)
Left analog X+ (right)
Left analog X- (left)
Left analog Y+ (down)
Left analog Y- (up)
Right analog X+ (right)
Right analog X- (left)
Right analog Y+ (down)
Right analog Y- (up)

So, we know this is “mapping” button presses & stick movements to the config file:
/opt/retropie/configs/all/retroarch.cfg

But so we’re clear, our Speed-link Competition Pro USB joystick controllers have only 4 buttons & 1 joystick which (when pressed) return the following values:

Bottom Right Round Button = “0”
Bottom Left Round Button = “1”
Middle Right Triangle Button = “2”
Middle Left Triangle Button = “3”
Joystick Left Move = “Axis 0, Value 32767”
Joystick Right Move = “Axis 0, Value -32767”
Joystick Up Move = “Axis 1, Value 32767”
Joystick Down Move = “Axis 1, Value -32767”

So can we go in to the config file & manually type these in & also delete any unnecessary ones? As the above procedure has was too many things for these joysticks.

Wow,
thanks for the SUPER-QUICK reply.

We’ve typed in the following code from the tutorial you mention above:

/opt/retropie/emulators/RetroArch/installdir/bin
sudo ./retroarch-joyconfig -j 1 >> /opt/retropie/configs/all/retroarch.cfg

But we get the following error:

Couldn’t open joystick #1.

Just so you know, I’m a very old motor mechanic, so my understanding of computers is very limited & my son is just starting out on his journey. So we are very appreciative of any help.
