Thanks!
Unfortunately,

jstest /dev/input/js0

does not trigger the turbo button, so I think it is an internal controller button. All other buttons trigger.

Have you tried using a wpa_supplicant.conf file? In retropie docs, see “Connecting to WiFi Without a Keyboard”. Works great on my Gpi. You shld probably remove your existing WiFi config before trying it.

I'm very late on this one but I had the same issue.

It's also been reported in GitHub (https://github.com/RetroFlag/GPiCase2-Script/issues/22) - there's a workaround there that worked for me.

@seatbeesate
I stand corrected, I did a fresh install again/installed safe shutdown script rebooted and seems to be working.

Going to try and reproduce to make sure maybe it was just the config.txt that got screwed up or something.

@EctoOne

Oh yeah. Will do. Thank you!

@G30FF

Thank you my friend. You saved me a bunch of wasted time. I would have had to dig deep since I did not see this documented when I read the specs.

I found this and got it installed. =)

@cdaters Was worried that would break some scripts, but it didn't, so yay!

I have also resolved the issue with using a bluetooth controller for ScummVM. The write up is in the other post. In case you also need it:

@sleve_mcdichael Thanks!

The Raspberry PI 4B with 8 GB of RAM. The performance gain is small for gaming because RAM is usually not the bottleneck

Eh? The performance gain past 2GB is zero. Retropie uses around 1GB with swap and all. The extra ram might help with installing emulators from source or if you want to use it as a desktop someday.

You need a compatible power adapter and lots of companies make them.

I only recommend the official psu due to reliability. They are $8US so there shouldn't be a reason to get a 3rd party psu that no one knows how reliable they are.

If you're going with a plain pi4, for a case, I recommend the argon one v2 if you don't want that nespi. It has a fan and converts the microhdmi ports into normal sized ones.

@mkp132 have you looked into running a mausberry switch? I have a Pi3b+ setup and running in and old Sears Super Video Arcade shell as the case. I installed the mausberry circuit and used the original console switch as the on/off. All you need to do is install the script and that should work.

You can even wire the mausberry off of the original cabinet power switch.

It might be easier and save you time to do it that way

@retrokada where do you get the firmware?

@Crush Thank you so much! That worked perfectly

I couldn't find any contact info for them.
I am very sorry, I was just looking for any help.

@MrCoffee The RetroFlag Snes controllers are the best aftermarket wired Snes controllers i have tested.

@studysession double check your GPIO connection. Also try switching to unsafe shutdown (switch in the case PCB) if you have that and see if you have it to power on.
