    I use the standard NES emulator and one problem I keep having is, that it is running painfully slow compared to most other emulators (SNES, Genesis etc).
    This is caused, I believe, by the resolution for NES beein higher than for the other emulators. The way I noticed this is, that when I save during gameplay in NES I can read the whole text of “Saved state to slot #0”. While e.g. playing SNES the text is much bigger to begin with, runs across the whole width of the screen and I can only read half the text.
    So, how can I change the resolution for the NES emulator? Or is there another way to fix this problem??

    And is there any way to save on Mame, using mame4allpi?? I googeld it but couldn´t come up with anything usefull.

    thank you



    Hey there.

    By default the config for NES is mode 4.
    # starttype==4: set video mode to 720p60
    Many of the other emulators are setup for VGA only mode which is starttype==1

    I haven’t actually tried adjusting this as my NES seems to run fine.

    The config file is located here: /home/pi/.emulationstation/es_systems.cfg
    Scroll down to this line – DESCNAME=Nintendo Entertainment System and you will find this line
    COMMAND=/home/pi/RetroPie/supplementary/runcommand/ 4 "/home/pi/RetroPie/emulators/RetroArch/installdir/bin/retroarch -L /home/pi/RetroPie/emulatorcores/fceu-next/fceumm-code/ --config /home/pi/RetroPie/configs/all/retroarch.cfg --appendconfig /home/pi/RetroPie/configs/nes/retroarch.cfg %ROM%"

    If you change 4 to 1, I believe that will change the video output mode, although I have tested this, just a guess that it will work but I assume that the emulator supports 480p output.



    I just tried this and it works perfectly fine now. So much better than before!

    Thank you
