Introduction

Features

* 1-2 Player Support
* Custom controller configurations
* SD, USB, DVD, SMB, GC Memory Card, and Zip support
* NES Compatibility Based on v0.98.12

Loading From DVD or Windows Network Share (SMB)

* ROMs can be burned to a DVD-/+R (4.7GB max size & ISO 9660 file format) but you need to install the DVDx on your Wii. More infos on HackMii.
* To load roms from a Windows network share (SMB) you will have to edit FCEUGX.xml on your SD card with your network settings, or edit fceuconfig.cpp from the source code and compile.
