    I downloaded Libretro from the builtbot https://buildbot.libretro.com/stable/1.3.0/nintendo/3ds/ and installed the .cia file for DOSBOX. Then I created a Folder called DOSBOX on the root of the sd card and put the game inside. This game: ( http://www.dosgamesarchive.com/download/jetpack/ )

    So I extracted the archive so it looks like this:

    Code:
    F:/DOSBOX
    │   FILE_ID.DIZ
    │   HISTORY.TXT
    │   JETDEMO.DAT
    │   JETLEV.DAT
    │   JETPACK.EXE
    │   JETPACK0.DAT
    │   JETPACK1.DAT
    │   JETPACK2.DAT
    │   JETPACK3.DAT
    │   JETPACK4.DAT
    │   JETPACK5.DAT
    │   JETPAL.DAT
    │   JETSOUND.DAT
    │   JSWITCH.EXE
    │   MANUAL.TXT
    │   README.TXT
    │   SAVEGAME.DAT
    │   SCLM.DAT
    │   TROUBLE.TXT
    │   _JETP_.DAT
    │   _JETP_A.DAT
    │   _JETP_A0.DAT
    │   _JETP_B.DAT
    │   _JETP_B0.DAT
    │   _JETP_C.DAT
    │   _JETP_C0.DAT
    │
    ├───LEVELS
    └───SQUAREZ
            DEMO.DAT
            FILE_ID.DIZ
            GRAPHICS.SQZ
            MANUAL.TXT
            SCLM.DAT
            SQUAREZ.EXE
            TROUBLE.TXT
    

    I launch DOSBOX and navigate to the folder, it shows the two .exe files, JETPACK.EXE and JSWITCH.EXE . I click on JETPACK.EXE and get this message:

    Is this user error or does it mean this particular game cannot be run? It runs fine on DOSBOX for my Windows 10 machine... I would love to play on the 3DS

    It crashed immediately? I tried it three times, it crashes with the Nintendo 3DS giving me the error message: An Error has occurred... and the console reboots.?

    I forgot to update the retroarch folder along with the cia version. So the game boots now, but I'm having the hardest time figuring out how to map the buttons. On a computer this game uses S ESC up down left right left CTRL and left ALT - I tried so many options but I can't input anything, the game just doesn't react to any button press.

    How to map the buttons?

    extract the retroarch folder in the 7z file to the root of your sdcard. This game is working for me

    yeah I just edited my post as I figured it out. Did you try the game yourself? Could you help me with the buttons? It's driving me crazy. I tried joystick, retropad, mapper. It doesn't react to any input

    Sure. I'm playing this game right now, kind of fun.

    First load the game. Then go to retroarch menu, config tab, input, Input user 1 and choose mapper.

    Back to the main menu in the first tab and choose quick menu, options and map your buttons down there. Pretty annoying but works.

    thanks, It works now. but it's not running at native speeds, I tried changing values in the clock speeds but it's either too slow or the framerate is so high that nothing seems to move at all.. oh well, would have been so much fun. This game has a level editor, it's basically Mario Maker for a game with very different mechanics!

    I'm using a new 3ds. Not full speed for me to but I think it's 80% (didn't try on PC so not sure)

    I know this is nothing new - but I only discovered today that we can play DOS games on a 3ds, with the Flashcard method it works perfectly! This makes me really happy :) Now I can replay all those 400 levels and create even more! Thanks!
