Metroid Advance Randomizer System

This repository contains the ASM changes needed in order to build a new Metroid Fusion ROM that allows, among other things, randomization.
To actually randomize things, you will need to use the Python patcher instead.

Running from Source

Prerequisites

Unix

• Build armips from source, and put the resulting binary into your PATH
• Put FLIPS into your PATH

Windows

• Build armips from source, and put the resulting binary into the tools folder as armips-a8d71f0.exe
• Put FLIPS into the tools folder as flips.exe

Compiling

To compile, place your US copy of Metroid Fusion into the root of the repo as metroid4.gba and then run make. This will spit out a new ROM into bin/m4rs.gba.
By running make dist you will additionally get an IPS patch of the base patch, as well as for some optional changes.
