Welcome to N64brew Wiki Homebrew Documentation!

N64 Homebrew Game development is getting better and this documentation is a key part of that.

Introduction

All of the individual parts are described in detail below and on their linked pages, but first let's describe what we can expect.

This is a great console if you want to do a 3D game with some constraints to challenge yourself.

The main CPU (R4300) runs at 93 MHz (not GHz)
The graphic processor (RSP) runs at 62 MHz
The system has 4-8 MB of RAM
The maximum commercial game cartridge is 64 MB, most games were 32MB or less
Maximum resolution 640x480 but most games were only 320x240
30-60 Frames Per Second
