hi :P I'm new here, and tired, so I'm sorry if I've messed something up! I recently bought a copy of My Secret World for the DS from a second hand store. It's a diary game aimed at tween girls, I enjoyed the idea of using this random game as my actual journal so I bought it. When I opened it on my 3DS, there was an existing save file (last opened 26 December 2013), but I couldn't access it because I didn't know the 4 digit PIN or the security question. I tried a bunch of super common PINs (like 0000, 1234, 9876 etc) but no luck. I erased the file (my new diary is going strong, it's actually a fun little game), but before I did I saved a backup with Checkpoint of the original save. I'm curious if there's a way of getting around that lock, without just straight up brute forcing? Is there anything I could use to look into this more? Honestly I'm most interested in the process (if it can be done) than the actual diary.

[Release] 3DS-CLI - Run a real RISC-V Linux environment on the Nintendo 3DS

cmdada · 2026-05-29T15:39:36+00:00

Hi guys!! I’m releasing 3DS-CLI, a Nintendo 3DS homebrew app that boots a real RISC-V Linux environment inside the normal 3DS Homebrew Launcher. It uses mini-rv32ima by cnlohr as a compact RISC-V CPU emulator, with terminal output on the top screen and a custom touch keyboard on the bottom screen. Features Boots a RISC-V Linux image on real 3DS hardware through software emulation VT100-style terminal output on the top screen Custom bottom-screen touch keyboard D-pad sends arrow keys Includes a prebuilt Linux image with BusyBox tools, a JavaScript runtime, and CLI Doom Installation Universal-Updater: 3DS-CLI can be installed directly from Universal-Updater. Just search for 3DS-CLI and install it from there. Manual install: Download 3DS-CLI_Install.zip from the latest GitHub release Unzip it Copy 3ds-cli.3dsx and Image into the /3ds/ folder on your SD card Launch 3DS-CLI from the Homebrew Launcher Wait for Linux to boot. On my SDXC card and 3ds ll it takes around 172 seconds to reach the login prompt. Log in as root with a blank password. Controls Bottom screen: touch keyboard D-pad: arrow keys START: exit back to the Homebrew Launcher This is mostly a fun technical experiment rather than a fast Linux machine. It is running through software emulation on 3DS hardware, so booting takes a while and performance is limited.

I’ve seen a lot about it having an 800x240 mode but see absolutely zero about HOW to do this.

Is 800x240 ALWAYS what the scaled top screen is? Is that why my bottom screen looks WAY worse (outside if pixel perfect mode) or is there something else wrong?

Dunno about 800px mode, but the top screen will look better because it’s wide enough that you can scale the GBA’s 240x160 up 1.5x on each axis to 360x240. The bottom screen is 320x240, so the max scale is 1.33…
