Multi-platform port of LEGO Island (Version 1.1, English) based on the decompilation project.

Note: An existing copy of LEGO Island is required to use this project.

Installation

Prerequisites:

  • Device is running custom firmware (Luma3DS). See instructions on 3DS Hacks Guide.
  • Device has a working touch screen
  • You have the game files. This guide assumes you have the mounted ISO on your system.

Instructions:

  • Copy the isle.3dsx file to sdmc:/3ds/.
  • In the 3ds folder, make a new folder named "isle".
  • From the mounted ISO, copy the /Lego/ folder to to sdmc:/3ds/isle/.
  • From the mounted ISO, copy the /DATA/disk/LEGO/ folder to sdmc:/3ds/isle/ (you want to merge the two directories). All the game files should be in sdmc:/3ds/isle/LEGO/.

Your SD card should have a tree like this:
