    TWLoader is a CTR-mode frontend for nds-bootstrap (and flashcards, if you have one.) that looks and feels like the Nintendo DSi Menu (theme can be changed to R4 or Wood).
    With this, you can run your NDS games, with the DS/DSi boot screen, and clock speed of 133mhz (faster than normal DS). No this is not an emulator.
    You can also change the UI color to your favorite color, and have glowing rainbow colors in the Notification LED.

    FAQs are at the bottom of the post.

    (Always updated)
    Scan these QR Codes:
    GUI
    TWL-NAND SIDE
    and Download here. (CIA files are in "sdmc:/_nds/twloader/cia/" if you skipped QR downloading.)
    NOTE: The 3DSX version does not launch games, due to it being impossible.

    Music files
    Put "music.wav" at "sdmc:/_nds/twloader/".
    Music must be 44khz, and 1 minute.

    Instructions
    1. Extract the files/folders in the "sdroot" folder to the 3DS' SD Card root. Do not extract the "sdroot" folder itself to the SD Card root.
    2. Put .nds ROMs in "sdmc:/roms/nds/". Create the folders if they don't exist.
    3. Dump the DSP firm, as that's needed to play the sound effects and music.
      Check here: https://gbatemp.net/threads/release-dsp-dump.423860/
    IMPORTANT NOTE: If you plan on do a system transfer, before you do it, uninstall the TWLNAND side app first, unless you want to keep using TWLoader on the system that had it's stuff transferred to the new system.

    (Optional) Run ROMs from your Slot-1 flashcard

    Custom box art instructions
    1. Create your .png file that's 128x115.
    2. Name the .png file to the same filename as the game, but with ".png" added to the end (ex. SD card: game.nds.png, Flashcard: game.ini.png).
    3. Save it to "sdmc:/_nds/twloader/boxart/" for games on the SD card, or "sdmc:/_nds/twloader/boxart/flashcard/" for games on the Slot-1 flashcard.

    This wouldn't have been possible without the following.

    FAQs

    Q: Is TWLoader a DS emulator?
    A: No. TWLoader is not an emulator (as stated above). When you launch a game in TWLoader, the system reboots into TWL mode, then switch to NTR mode for running your selected DS game (via the backend nds-bootstrap if ROM is on SD card).

    Q: Why is TWLoader taking me back to HOME Menu after updating itself?
    A: Some versions of TWLoader have a bug where it always updates itself to the latest version, even if it's already on the latest version.
    To fix this, either turn off Wifi and turn off auto-update TWLoader in the settings screen, or open settings.ini, and set AUTODOWNLOAD (in [FRONTEND]) to 0.

    Q: What's the TWLNAND side CIA? Does it patch TWL_FIRM?
    A: No. It's a DSiWare app only used by the GUI (not seen in HOME Menu). The TWLNAND side has the boot screen, and starts bootstrap for running the ROMs, and it's own NTR_Launcher for running Slot-1 games/flashcards.

    Q: Why do I get a white screen when trying to load a game from SD Card?
    A: Lock ARM9 SCFG_EXT isn't off. Make sure Lock ARM9 SCFG_EXT is off.
    Also, please note that not all games work from SD Card yet. Check the list above.

    Q: How do I run a game in GBARunner2?
    A: Put your SRAM-patched GBA ROM in the SD root as "runner.gba" and put the BIOS in the SD root as "bios.bin".
    To SRAM-patch your ROM, use GBATA.

    Q: Why is there lagging when picking a game?
    A: The previous/next boxart and icon images are loaded, instead of them being loaded all at once. This is done to prevent memory leaks.

    Q: Won't the LED feature cause an MCU brick?
    A: Don't worry. @MarcusD said that you can only MCU brick on firmwares 8.1 or below.
    It's confirmed there aren't any bricks above 8.1.

    Q: Why am I'm getting the error screen when launching a game?
    A: Make sure you're using an up-to-date CFW, namely Luma3DS.

    Q: Why do I get a black screen when launching a game?
    A: I dunno, but please follow this guide. https://3ds.guide/troubleshooting#twl_broken
    If you're using a boot manager to boot Luma, such as BootAnim9, look here.

    Q: Why do I get an auto-shutdown when launching a game?
    A: It's due to a pre-patched TWL_FIRM still being installed. Follow this guide. https://3ds.guide/troubleshooting#twl_broken
    If you're using a boot manager to boot Luma, such as BootAnim9, look here.

    Q: Will there be a way to return to the TWLoader menu while playing a game?
    A: No. It will require hacking TWL_FIRM, which may be hard.

    Q: How do I update TWLoader on the 3DS?
    A: To manually update, press START in TWLoader settings.

    Q: I'm getting a bootstrap not found error?
    A: In settings, update the bootstraps, then in NTR/TWL settings, set Bootstrap to Release, then to Unofficial (or vice-versa).

    Sadly, it's only homebrew and download play for now.

    No, meaning DSiWare can't be launched with this.
    Yes.

    ROMs, as the file in the folder says.

    EDIT: Thought you said "folder", not "loader".
