!!!INTENDED FOR SUPER MARIO BROS. ON THE NES!!!
*created by CardiganHill*

INTRODUCTION
============
This is a rudimentary patch that swaps Mario and Luigi ingame with accompanying modifications to game text, screens, and HUDs. No changes have been made to the game's mechanics.

ENCLOSED FILES
==============
This patch comes in two flavors.
~The easiest and least tedious file to use is the luigiedition.ips file. This patches your .NES files directly without needing to punch in individual codes. You will require an IPS patcher to use this file. I'd recommend Lunar IPS, which you may obtain at http://fusoya.eludevisibility.org/lips/
~This patch also comes with a set of 26 Game-Genie-format codes in the gamegeniecodes.txt file. These may be decoded by your emulator, an external website, or Game Genie hardware to apply some or all of the patch. This file is annotated so you can choose which elements of the patch you'd like to apply.

I also included the patch screenshots because why not?

COMPATIBILITY
=============
This patch has been tested on:
-Super Mario Bros. (World) (NTSC)
-Super Mario Bros. + Duck Hunt (USA) (NTSC)
-Super Mario Bros. (Europe) (Rev A) (PAL)
-Super Mario Bros. + Duck Hunt (Europe) (PAL)
This patch works on all editions and regions.
