About LEGO Island
Needs the files from your own copy of LEGO Island. The English version 1.1 is what the project is based on.
isle-portable takes the LEGO Island decompilation and swaps the Windows-only parts for SDL3 and other portable libraries, so the same game runs on the 3DS and a long list of other systems. The aim is to keep the game as it was, without changing how it plays or rewriting code just to improve it. Small mods are possible through extensions.
The project has a guided installer that goes through setup for each system step by step. Releases are built from the latest code as it lands, so the team warns something may break now and then.
