@guestdreemurr how are you trying to install? RetroPie has to be installed within a preinstalled supported Linux OS (Debian/Ubuntu/Linux mint etc).

See the instructions in the docs https://retropie.org.uk/docs/Debian/

@tinyunknown156 The weirdest thing here is that you are gonna use a mame version from 22 years ago on a pi4 : the older the glitchier. While mame2003+ has a good balance between supported games, fixed bugs and performances on a pi4, the same is not true about the other vintaged mame cores from over a decade ago.

@romhackfanatic Yeah bangai-o stuttering is usually a lack of bios. You just need to download the dc bios, create a dc folder in retropie's bios folder, and then put dc_boot and dc_flash inside it.

@dankcushions said in Pi 4b black screen issues:

@luisdent like i said, show us your config file and we can diagnose. there's an extra few lines that helps on some monitors:

hdmi_max_pixel_freq:0=200000000 hdmi_max_pixel_freq:1=200000000

in addition to a working 1080p mode, which for you may be

hdmi_group=2 hdmi_mode=82

ps, can you not SSH in to diagnose via another PC on the network?

Not sure which fixed it, but this made it work properly. It flickers a screen with the terminal/command cursor a few times quickly but i see it and then it displays the appropriate screen following that. So far i've gone in and out of config screens and reboots and it appears to be working now.

Thanks!!!

Now to fix the performance issues ;-) or i should say optimize. it runs fairly well. :)

@itsthex said in Controller Issues - Buttons Inop, Controls change:

I picked up a Vilros Pi 4 kit to use with VMAN's 512gb image. Consensus seems to be that one shouldn't use a prebuilt image, but I figured I couldn't go wrong with what was seemingly regarded as one of the best. And, so far so good!

We don't support 3rd party images. Ask the author(s) of the image for support, or use the image from retropie.org.uk/download.

Connect it in Xinput or Switch mode, re-configure it in EmulationStation, and see if the issue persist.

@pedrovay2003 well the keys were leaked many years ago. Possible that they are in there. Or they have some hackey way of decrypting like the programs that will extract a clean iso from a bought pbp.
You may be the one of the very few people to attempt to run a DRMed file in an emulator, because for the most part, it should not work.
Also beetle-psx is practically the same emulator as mendafins.

@ashpool Ok thank you! I was worried there

@pjft said in Problem with backup using Windows:

@retrus You may use rpi-clone to clone your card to another, smaller one, and then run the backup on Windows.

Thanks for advice. I bought 2TB ssd :)

@dmg9626

OMG! IT WORKED 🤯

For the record this fixed my Retro-bit "SEGA Saturn® Bluetooth® Wireless Control Pad - Slate Grey" pairing issues with my rpi 4.

TYVM dmg9626 u the man 🥳

@dankcushions looks works fine in Colin Mcrae Rally 2 when widgets are off.

@rbezares I had this a couple of days back, somehow es had managed to remove it self, I refreshed the card and it happened again, although got slightly further in the boot as es did appear before crashing. I flashed a new image to a different micros and it has worked fine since so am putting it down to a bad card

@mitu thank you! So once I do this, it will allow me to choose if I use the joystick/controller for a game? Do I have to input the user binds for each input?

@dankcushions thank you so much for giving me this link... i finally found compatible roms. I am so thankful like, omg, i can finally continue my project. You made my week!

Hello and welcom to this forum.

Did you configure the controller via Emulation Station correctly? Maybe do it again to be sure. There's a script to assign controllers to players. It works very well for me. Maybe it's worth a try for you.

If all of that doesn't help, please give us the information that's asked for in https://retropie.org.uk/forum/topic/3/read-this-first.

Update: Installing Retroarch from source seemed to do the trick.

OKAY... That Problem was so uncivilized.... All I had to do was use putty and DONE! That's it!

Ok I understood what was happening.
There were two more optional Dreamcast emulators that I missed installing.

The games that were not booting in the Reicast run well on the other two. :)

@Rancid84 said in Pi 3 b to Pi 4 b:

I just bought a R4 and have an img from R3 downloaded from arcade punks. Are the previous comments still accurate to use this IMG from R3 over my R4?

Third party images are not supported. Do so at your own risk.
