http://www.gameanyone.com From the readme file: A demonstration of how to create an MMC1 multicart containing three NROM games and one MMC1 game Animal Crossing Population Growing, a game for Nintendo GameCube, contains several emulated NES games originally published by Nintendo. Using the third-party Action Replay accessory, ROM hackers have found the data for several games that are never unlocked in the normal course of a run through ACPG. These four games are Mario Bros., Ice Climber, Super Mario Bros., and The Legend of Zelda, which are called the -forbidden four- among Animal Crossing players. Forbidden Four Multicart allows the user to put these games (or in theory any other NES games) into a single ROM. == How to build a ROM == 1. Put two NROM-128 games (as shown here Raid on Bungeling Bay and Lunar Pool) in iNES format named "bros.nes" and "ice.nes" in the same folder as "menu.nes". 2. Put one NROM-256 game (here Magmax) named "smb1.nes" in the same folder. 3. Put The Legend of Zelda: Outlands (or possibly other select games) named "loz.nes" in the same folder. 4. Run -Build Multicart.bat-.
