@mitu you are a miracle worker!!!! working perfectly now. thank you so much for all the help. :)

Great, thank you very much @BuZz !!

@gogangdong said in RPI4+GPIO acting strange:

4.5.13

The hardware was wired to the GPIO for the wiring of the mk_arcade_joystick_rpi and the mountains and joysticks, Sanwabuttons a,b,x,y,l,r,start, and select buttons to fit the GPIO and install 4.5.13 (https://files.retropie.org.uk/images/weekly/).B,Y,Other buttons on joystick did not work.
mkarcadejoyystick 0.1.7 version(https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/supplementary/mkarcadejoystick.shSetup/blob/master/scriptmodules/supplementary/mkarcadejoystick.sh

In the input setting of the retropie, say you found the GPIO controller and enter the keystroke (if you press Y, GPIO).They say they found the controller and enter the keystrokes. The joystick and other buttons do not work and the key setting sets the joystick to the top and B buttons, and the other buttons do not work.)

@AlphaBetaPie Post the theme so we can test and see if memory is an issue or maybe there's something else.

@mitu : Thanks, makes perfect sense. I suspected it was something like that.

@YFZdude

Yes I tried turning it on.

Really whatever I do makes no difference. I think it’s just something screwy in windows, I hate windows.

Scraping the way previously described worked perfectly, thank you as usual mitu.

Any chance someone could translate this fix in to layman's for a newbie?

The only applicable advice in the above topic is

uninstall es dev, reinstall regular binary

Try re-installing your EmulationStation package, either from binary or from source.

So,, I tried the advice here from both Binary and source. I even removed all exp packages just to ensure it wasn't anything in there. The error still appears and now i've decided to attempt a complete rebuild from Raspbian up. I am also increasing SD capacity from 16gb to 32 GB to ensure space isn't an issue.
So, I did a basic install and then removed all main packages then proceeded to reinstall the main packages from source. See what happens there

Oh, yeah, forgot it's using $md_inst for user data.

That's a fortunate coincidence :).

@filippoaceto said in Install retropie on ubuntu:

Is there any way to install retropie on pi4 with ubuntu?

No, on a Raspberry Pi only Raspbian is supported.

@corezon Not sure if you're still looking into this, but flycast vmus are stored under ~/RetroPie/BIOS/dc/. The documentation is a little fuzzy on this point, but it does talk about it:

@mitu thanks at least I know I am not crazy!

Yeah playing on a PC for lightgun games and lightgun support is wonky for other mame versions and for various reasons not wanting to do advance mame. I use mame-2003-plus and fb alpha on the pi.

@pjwentink We don't support 3rd party images and links to ROM sites are not allowed by the forum rules You'll have to ask the image author for compatibility and please remove the link to the image.

Thank you @mitu. I would never have guessed that setting controlled it. Works like a charm.

@taz101 you probably will need to configure controls after, I did with my bartop and made custom screens to show the controls while the game loads. Makes playing a lot easier.

Hyperpie is Retropie with Attract Mode and themes added ready to go, you can get the base image for it for free so don't pay someone for it.

I agree with both of you @Evert and @shavecat, the one I'd really like to make work with hi-res textures is Mario Kart 64 :(

Nobody?
