regions on .rom files?



  • This might be a dumb question, but here goes:
    I am experiencing some issues with input delay when playing several NES and SNES games on my Raspberry Pi Zero W. I'm playing on a PAL TV, but all of my .rom files are NTSC, so I was wondering if this can cause me any issues when emulating with retroprie?

    On the other hand, it might just be the games controls that are too "clunky" for me, since I really don't remember the feeling of the controls on the original consoles. Hope you can help me!

    There are timing differences with PAL vs. NTSC ROMs, but I've never heard of it producing noticeable input lag. I would employ a little trial and error here and see if the PAL ROMs give you a different result. First and foremost, make sure that if you're using a modern TV, it isn't doing any kind of post processing on the audio or video. Many televisions will have a "game mode" setting for this very purpose.



  • After trying some PAL ROMs it all way more responsive, so it might just have been the region. But when I play the games there are some sound issues now. On NES games the music plays way too fast, and on SNES games, there are minor issues with the sound.

    I can't speak to the SNES issues, but I believe both lr-fceumm and lr-nestopia need to be aware that a game is PAL before they will play at the correct speed. If I remember correctly, lr-nestopia achieves this by checking the NstDatabase.xml file in your BIOS folder and lr-fceumm checks for "PAL" to be included in the file name. Outside of that, you can also force PAL from the core options in the RetroArch menu as well.
