About

A Nintendo 3DS dual-screen port of The Legend of Zelda: The Minish Cap, based on the open-source Minish Cap decompilation, Project Picori and a dual-screen Android port. No ROM or extracted game assets are distributed, so you must provide your own legally obtained compatible Game Boy Advance ROM.

How it differs from the original

Adds true widescreen gameplay on the 400x240 top screen and a bottom-screen interface with a live map, dungeon information, quest status and touch item controls. It supports both USA and European ROMs and includes European gameplay backports without needing a patched ROM. New Nintendo 3DS models get extras such as 804 MHz mode, multi-core rendering and an optional C-Stick turbo.

Getting started

Install the CIA with FBI, or use the 3DSX build with the Homebrew Launcher, then create a folder for the game on the SD card and put your USA or European .gba ROM inside. The European ROM is recommended because it received the most testing. Audio needs a working 3DS DSP firmware setup.

Known issues & limitations

The opening Picori legend leaves the bottom screen black, and the overworld map shows only its stone frame until Link receives it.
Full View is experimental and works only in compatible outdoor rooms and supported interiors.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Nintendo 3DS version).

A working Nintendo 3DS DSP firmware setup is required for audio.
