Problems with PrBoom on retropie, although it works, the screen graphics are a mess, with vertical lines and what looks like noise pixels over much of the image. Although these noise pixels are not random because they stay with an object wherever that object is on the screen.
If I do a screen shot the image is fine, and if I run it on an HDMI TV it is also fine.
I would think it is the monitor but most other stuff (including duke3d) works ok.
I also did a separate install of PRBoom using apt-get and that works fine too.
So in what is the difference. I already tried all of the config.txt settings suggested for HDMI problems. ( I’m using a DVI-D monitor)
Well first you need to get some doom wad files, these are not included in retropie.
They need to be copied to RetroPie/roms/doom. then when you run emulationstation you can select the doom wad you want to run and it should work.(don’t select the prdoom thats already there, it doesn’t do anything).
The easiest way to get the roms copied onto the pi is to insert a blank formatted usb memory stick into the pi usb with emulationstation running. It will create a rom folder on the usb stick, with sub directories for all emulators.
Remove the stick and plug it into a pc, where you can copy the wads ( or any other game roms ) to the appropriate folder. plug the usb back into the pi and it will automatically copy the roms to the correct folders for you.
