    I finally modded my 3ds so I can makes files of my 3ds games to play in retroarch. After I make a file of my 3ds game I scan for the file using retroarch but it won't detect the game. By the way I'm trying to make a file of Pokemon Alpha Sapphire. Why won't retroarch detect my file. Sorry if I'm not giving enough detail.

    What do you mean by nkt. Is that a file type.

    No its clearly a typo which should have been not instead of nkt. To clarify retroarch plays retro system games NOT 3ds.

    I know Libretro has a citra core for PC, but I didn't know it had a Citra core to play 3DS games on a 3DS. Kind of like playing PS1 games on an emulator that runs on a PS1.

    No I'm playing trying to play my 3ds games on my PC. Sorry for the confusion. I had to mod my 3ds so I can make files of my 3ds games to play on my PC.

    I know I could but I really like retroarch because it does several emulators in one. Plus I really like its user interface.

    So the issue is with retroarch on the pc? So this thread should be in the pc section and not in the 3ds homebrew section that is why people got confused as to what you are trying to do.

    Okay I'm sorry I though this might be the right place since I'm trying to use a 3ds emulator on my PC. I want aware there is a PC section.

    She could technically reply at the thread:
    if Citra core is inclusive.

    ***

    @GalaxyDreamer90, I would really consider using the native Citra emulator over RetroArch because RetroArch adds another layer of complications.

    RetroArch is usually good with well established classics and oldies cores.

    ***

    For Citra, dumping the 3DS cartridge games as *.3ds format should be trimmed and decrypted.

    Okay thanks. Unfortunately it says I can only make one topic a day. I guess I'll ask there tomorrow or Wednesday since I'm usually busy Tuesdays.

    How do I trim .3ds files that might be why retroarch isn't directing my .3ds file.

    Look up how to trim 3DS files. There are a few, including 3DSExplorer, and this page here: https://gbatemp.net/threads/3ds-rom-tool-rom_tool.349314/

    @GalaxyDreamer90, there's a way to trim and decrypt *.3ds game roms in GodMode9. I don't remember the exact step-by-step in dumping those roms from physical 3DS carts as I no longer own any to verify.

    Instructions in dumping a trimmed *.3ds can be read here:

    However, if you downloaded a full size & encrypted *.3ds rom from the Internet, you may:
    • NCSD image options... → Trim file
    • NCSD image options... → Decrypt file (...) → Decrypt inplace

    I tried trimming the file and also following the instructions in the link above and retroarch is still not detecting the game file.

    Have you tried the games on Citra directly instead of through retroarch's? And have you tried to load the game through Retroarch's normal menu or through it's desktop window?

    Yes I have tried it on citra directly and it works fine. And I try to load the game in retroarch through it's normal menu. How do I open it through it's desktop window.
