JoiPlay is a launcher for Ren'Py, RPG Maker XP/VX/VX Ace/MV, TyranoBuilder and HTML5 based games. Ren'Py and RPG Maker XP/VX/VX Ace support is seperated from app to make app modular and these game types can be played after installing plugins.

JoiPlay has some unique features which creates a better experience for players.

- Save files from PC are supported for all supported game types.
- Built-in cheat menu injection for RPG Maker MV games.
- Commonly ussed Node.js classes/functions are supported.
- Commonly used Win32Api functions are supported on RPG Maker games.

JoiPlay does not include any games and requires legally obtained game files to play them.

JoiPlay supports Ren'Py, RPG Maker XP/VX/VX Ace/MV, TyranoBuilder and HTML5 based games and several factors effect game compatibility. JoiPlay doesn't emulate Windows so games that depend on Windows APIs or uncommon Node.js classes/functions won't work. Estimated compatibility rates are 50% for RPG Maker XP/VX/VX Ace and %90 for other game types.
