    I would love online multiplayer to be available for this project. I could swear that some of the SNES emulators i used to play as a kid on the PC about 15 years ago were online enabled, ZSNES or SNES9X offered online capabilities, so you could connect to players over the internet via the emulator and then play together.

    There were the occasional problem with de-sync or lag, but in general a save state and reconnection would sort that out.

    I would love to see this a as an enhancement request of RetroPie

    Just thought I would let people know in case they come across the same issue on the NES, that I have resolved the issue to a degree on RetroPie 2.6.

    I came to play battletoads and this one was missing the top and bottom of the screen so no health or score was visible, unfortunately 2.6 only has 1 NES emulator, so floob’s suggestion of switching the problem ROMs to another emulator folder isn’t possible with 2.6

    I edited the opt/emulators/configs/nes/retroarch.cfg file with sudo nano and added the line below to the file

    video_overscan_crop = false

    I then restarted the emulator and tried again and this time the whole screen was visible so success and I have fixed the issue. I rechecked castlevania and the whole screen was now there as expected this time.

    The only downside to this is that as this is a global NES retroarch emulator config change, all NES games now have no overscan cropped, so Super Mario Bros 3 for example had overscan visible on the left and bottom side of the screen similar to the article floob posted previously.

    However I would rather have more of the screen than needed visible than missing some like scores or health bars etc.

    Hopefully this will help others having the same issue on 2.6

    Many thanks Matt

    Interesting find on that article, regarding cropping differences between certain games and lack of a standard on the NES. When I try SMB3 on RetroPie the cropping is there (according to the article) and is correct, and there is no part of the needed viewable screen that is missing, so the emulation seems perfect in regards to the video output.

    Thanks for all your help floob.

    Okay thats cool, not to worry I have seen a vid before on how to change the emulator in a config file or move the rom to a different folder, so I will try that.

    It was mainly driving me crazy trying lots of things to do with video output to sort it and nothing helping.

    Do you think it is just this game and the default emulator as opposed to all games? I have tried a few other NES ROMs and not noticed it, but with some games it’s not always as obvious as it was with castlevania because of the words missing letters.

    Just wanted to say a big thankyou for your help and really quick responses so far, you’ve helped put my mind at rest that my setup is right (as much as it can be) and it just happens to be the first game I tried to play properly that had a slight issue. If it’s fine with nestopia you can close this one off as solved as I will just use that for this ROM :-)

    Thanks again Matt

    I will try now, so did you get the same for that game missing parts of the screen, as i would like to know if it is a global thing or if it is just my setup?

    I can’t see an option to change emulator when pressing x, just video res for emulator, game or rom.

    Cheers,
    Matt

    Thanks for the reply. I have tried everything back to defaults so that all is hashed out, the screen resolution changes and I get the black borders round the whole picture (top, bottom, left and right), then made sure the emulator resolution option is also set to default, but I still lose the same amount of relative screen edge what ever settings I choose.

    It’s a 720p TV, full resolution is 1366 x 786 which I have also tried setting manually in the config.txt with the same issue. Other emulators seem fine, it just seems to be the NES

    What happens if you try and launch castlevania on the NES? Would be interested to see if it is just that game/rom and if it’s reproducable?

    I will try another TV but I don’t think it is the set, as everything else (raspian, emulationstation, other consoles) seem okay, with no overscan or screen missing.

    Thanks again for trying to help. I could probably put up with it, but as most NES games are a decent difficulty and reaction based, losing a bit of the screen, really hampers my progress, the turbo tunnel doesn’t need to be any harder :-S

    Hi floob, it’s your vids I have been watching and following which I have found incredibly helpful.

    It’s really hard to explain the issue but the x or m on emulator start (although changing the resolution) doesn’t help with the issue. Can you see in the castlevania image I attached how instead of the top left saying “player and enemy” it says “layer and nemy” it’s because the left side of the screen is cut off. It’s not cut off the TV as there are the normal black borders of a 4:3 screen on a 16:9.

    If I use retroarch menu to change top left and bottom right it simply stretches what is already there, it doesn’t show any more of the picture.

    Any ideas?

    Just to add to this, i want to keep the 4:3 aspect ratio and the resolution that the screen is running is 1280×720 and as said in the OP changing these to other settings and the issue still happens.

    Emulation Station runs in 16:9 and there are no edges missing with that etc, i dont think this issue is to do with the retropie video output / settings but more likely to do with the libretro/retroarch settings for this specific emulator. Just hoping someone out there will be able to understand this and help me out.

    Matt
