Please more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

Include the name of the game/emulator that have this issue. Does it happen for all games or it's just for some of them ?

@mitu Thanks for the suggestion. Tried that already previously but it didn't work, but I will give it another go. I hope the new HDMI cable will fix the issue.

@mitu thanks I will try that

@tzinck the link I shared mentioned how to retrieve the verbose log.

Ok, thank you. I'll give a try with those options.

@UberLumby seems like the usual incomplete neogeo.zip issue

@domi said in Pi4 N64 Bomberman 64 Blackscreen Workaround:

But the game does still not seem to run. Am I doing this corectly?

No, the core options are not part of RetroArch's configuration file. Start the game, then open the RetroArch's menu (RGUI) with F1, go to Options, where you can change the settings as mentioned before. After that, choose the 'Create Game Options' entry to ensure they'll be automatically saved for that game.

Thanks, Isn't it strange that with no SD card inserted it comes right up on the TV? Thats what has me so confused and it used to work fine on my RCA TV. I never have been able to get it working on the Bravia or Samsung. I had done that before, but I used Escher. MAybe that's the issue. I'll flash with the official one.

Appreciate the help.

@doctorbeefy said in Majority of screen hidden when launching game:

Bumping this as I am having the same issue. Anyone come across a fix? it seems to only happen for Sega Mastersystem/genesis and lr-genesis-plus-gx, other systems and cores work fine.

For most people, this glitch is something that originates in RetroArch and needs a fix. A future release of RA will probably take care of it. In the meantime here is a workaround:

After the game starts and you see this happen, use (Hotkey + "B") to reset the ROM. It should come back with the whole screen visible.

It's ok now, thank you :-)

@mitu omxplayer accelerator was already on so i turned it off to see if it worked but it didn’t

@yaya said in Pi 4 Black Screen after autostart:

may you should add this information into the FAQ ;-)

That's not a bad idea - we'll have a PI4 specific page 'really soon'. Have fun !

This is my screen:
http://www.lcdwiki.com/4inch_HDMI_Display-C

And I think this set of commands will install the driver:
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./MPI4008-show

They have 2 drivers for the 4" screen, so I'm hoping that points to the right ones.

Yesterday i installed the newest image of retropie.

Which image is that ? The PI4 is not supported by the official image.

After that i plugged it in on my 4k LG TV with a Micro-HDMI cable.

Which HDMI port have you used ? The Pi4B has two of them, it's recommended you use the 'primary' port, the one next to the USB-C power.

@ElRafilla It's not exactly the same issue - the poster didn't have any video output, you seem to have it working until launching a game. Open a new topic and add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first.

@xmrdarky Can you please fill in the information as requested here (https://retropie.org.uk/forum/topic/3/read-this-first) so people on the forum can try and help. Each setup can be wildly different and knowing all this goes a long way to assisting. Like @rbaker says, it sounds like it could be a power issue if you are running it just off a USB charger, such as a phone charger, but we wont know unless you give details.

Though not entirely the same configuration (it was a Pi 4), I encountered an issue wherein after the boot sequence the display would be completely blank. I eventually narrowed it down to the memory split setting - I had changed it, trying to follow the instructions for RetroPie 'manual installation.' Keeping it default resolved the problem.
