January 15, 2025 ยท View on GitHub

Note: Rewrite is currently work-in-progress. There may be issues, bugs, and crashes. You're using this at your own risk until I consider it finished. This is a work-in-progress rewrite and partial backport of the Switch version. You have been warned for the time being.

Quick start guide:

Global controls:

  • Pressing the L or R shoulder buttons will change what save data type is currently being targeted or take you to the settings menu.
  • Pressing Start will exit JKSM.
  • Pressing Select will allow you to set your play coins to whatever you want (for now).

Title selection(s):

  • Up, down, left, and right will change which title is selected in both Tile and Text selection mode.
  • Pressing A will open the currently highlighted title for backup and restore.
  • Pressing X will open a small menu with a few extra options such as erasing save data, exporting and importing secure values from SD.

Backup Menu:

  • Pressing A while "New Backup" is highlighted will open the keyboard and allow you to create a new backup.
  • Pressing A while an already existing backup is highlighted will allow you to overwrite that backup with a new one.
  • Pressing Y while an already existing backup is highlighted will allow you to restore the data contained within it.
  • Pressing X while an already existing backup is highlighted will allow you to delete that backup from your SD card.
  • Pressing B will close the currently open title and exit the backup menu.

Settings menu:

  • Pressing up, down, left, or right will change which option is highlighted.
  • Pressing A will toggle the option highlighted to On or Off. A short description of what each option controls is printed on the bottom screen.
  • NOTE: ZIP support is only semi-functional at the current point in time.

Building:

Building JKSM requires installing DevkitPro for your respective platform and installing the following libraries:

3ds-sdl
3ds-libpng
3ds-freetype 
3ds-libjson-c
3ds-curl
3ds-libzstd
3ds-zlib
3ds-minizip

With those installed run the following command:

git clone --recurse-submodules https://github.com/J-D-K/JKSM.git

This will clone my FS Wrapper library along with JKSM's source code. Then, navigate to the JKSM directory and type the following command:

make -j

You should now have JKSM.3dsx inside the JKSM subfolder inside the repo on your machine.

Customization:

JKSM currently uses Google's NotoSanJP font for drawing text. This font is rather large. If you would like to use a different or smaller font, simply build the included fontcompressor program and replace the font in JKSM's romfs when building it.
