EasyRPG Player is an open source implementation of the RPG Maker 2000/2003 engine. Get a RPG Maker 2000/2003 game and place it in a direct subdirectory of the Player (boot.dol). After starting the Player a game browser will launch and you can pick the game. Valid games have the files “RPG_RT.ldb” and “RPG_RT.lmt”. You can also launch Player in standalone mode by placing the game directly in the Player directory.
Changes and release notes can be found here. The program has been updated few weeks ago in March 2019.
