N64 no video or run command after upgrade from 3.8 - 4.19



  • Pi3b, home formatted image. Upgraded using preferred method from 3.8 to 4.19. 3 amp power supply, n64 overclock applied.

    1. Upgrade from 3.8 to 4.19 using the preferred method.
    2. After the initial upgrade it appears to work. After adding PS3 controller or several shutdowns that the video will not render for n64. I get a couple of colored vectors and then blank screen.
      I can see the game image prior to the video issues but also cannot enter the run command menu. I have confirmed that it is enabled. I have tried uninstalling lr-mupen. and reinstalling mupen64plus. I have tried removing the mupen config.

    All other emulators work and n64 works in 3.8

    Another note: mupen64plus does not show up in the sdl dispmax menu for me to enable. I would like to take advantage of the improvements in v4.

    if you have the image active you have to press the button after the image is displayed. just keep mashing it. the button you use depends on your controller (it's whatever is button 1 or 0 i think). for my ps4 controller it's the square button.

    there's no improvements. dispmanx is already used for scaling in mupen standalone.



  • @dankcushions thank you for replying. Mashing the buttons etc. does not work. I can record a video and put it somewhere if that helps?



  • @GinJa could it be that my config is bad and gets updated when I update my roms from my flash drive?



  • I had something similar happen and it was resolved per this post: https://retropie.org.uk/forum/topic/4321/runcommand-blinking-cursor-no-launch-menu/43

    To Paraphrase:

    "try adding plymouth.enable=0 to the cmdline.txt"

    The file is in the /boot directory. I had to add this to get runcommand back after an upgrade a month or two back.



  • Its already there. Try removing it?



  • @GinJa You can try removing it to see if it makes a difference. They must have added it into one of the updates.

    There is also the Runcommand configuration in the runcommand configuration option in the RetroPie area of Emulation Station. I suppose it's possible it is disabled in there for some reason.



  • Already checked that and the option is enabled. Reminder it trys to load the rom, I get 2 single pixel colored lines then blank screen. All other emulators work. I have not made any runcommand changes to n64.



  • is there a way to restore defaults? Could adding the PS3 controller mess up the inputs?

    It's possible that a controller would affect inputs, but that would generally mean you have no buttons within an emulator.

    At this point I would probably try and dig up another microSD and put a fresh image on it to see if it would do the same thing. I hate starting new though because I personally have a lot of game saves and tweaked configs I would have to back up or recreate. The last time I went with a clean setup, I lost my good customer crt-pi shader file.

    Hopefully someone else might have a better idea to spare you from that.



  • Wow you have game saves. All I do is try to fix issues on this damn thing. Game play is like 10%.



  • @GinJa The last time I broke everything, I lost a good 20 hrs back into Gran Turismo on Playstation (after finding my original PSX memory car with a 1000+ hr save file had been destroyed).

    Now if I had to reformat, I would have to deal with multiple save states a my son and I use them so we can play the same games.

    I'm still more mad about my cr-pi shader config file because I had it perfect for curved and regular on a 720p TV. I finally got another decent one for non-curved and kinda stopped at that point to play more games.

    To be fair, I have a TON of games on the Pi and mostly Play Devil's Crush Pinball or Multiplayer Bomberman 93.



  • Thoughts on Lakka?



  • @GinJa Never tried Lakka. It's probably worth a try to see what it's like. I'm kind of stuck in Retropie land because I have invested significant time in learning configs and it's Debian based which is the Linux distribution I have the most experience with.



  • removing the last line from the txt file worked. But now I see login for retropie just before the game starts.

    At one point, my Retropie setup did that as well. I can't remember if it still does, but that never really bugged me enough to look into it.



  • @mrbwa1 now I see retropie login and runcommand does not work. Think it might be time to switch to recalbox. No dreamcast but at least I will be playing more than investigating and being frustrated. 90% configuration = no fun.



  • wanted to add that when I launch the file-manager I am taken to the boot up screen with all the green ok's.
