Pokémon classics get new features via companion app including cross-game PC

PKsinew makes it easy to transfer Pokémon from one game to another

Classic Pokémon games, including FireRed, LeafGreen, Ruby, and Sapphire, are getting a new companion app called PKsinew. The software makes it easy to transfer Pokémon from one game to another, and it can also unlock events that wouldn't be accessible otherwise.

While Nintendo is reportedly working on releasing Pokémon FireRed and Pokémon LeafGreen for Nintendo Switch and Nintendo Switch 2, developer Sebastian Santabarbara has released an open-source app that is intended to add a range of useful features to third-gen Pokémon games.

The software is called PKsinew and can be opened at any time while playing Pokémon FireRed, Pokémon LeafGreen, Pokémon Ruby, Pokémon Sapphire or Pokémon Emerald by pressing the Start and Select buttons at the same time. The app offers a range of useful features that are supposed to make these Pokémon classics more convenient. It starts with a Pokédex that collects data across all games, which makes it easier to complete.

Up to 2,400 Pokémon can be managed in the app and sent to compatible games

Moreover, the app provides additional data on Pokémon and allows them to be traded between games without needing multiple copies of a game and two Game Boys. The most interesting feature may be the PC system that lets gamers store up to 2,400 Pokémon in the app instead of just in individual games. Therefore, Pokémon can be managed independently of specific games and save files and sent to the desired game as needed.

The app also adds achievements to Pokémon games. It is also possible to unlock event tickets that Nintendo only distributed for a limited time, for example to catch Mew, without any cheat codes or mods. PKsinew can be downloaded now on GitHub. For now, the app only runs on Windows, macOS and Linux, and it requires a somewhat more cumbersome setup that is explained in the GitHub description.

My fascination for technology goes back a long way to the Pentium II era. Modding, overclocking and treasuring computer hardware has since become an integral part of my life. As a student, I further developed a keen interest in mobile technologies that can make the stressful college life so much easier. After I fell in love with the creation of digital content while working in a marketing position, I now scour the web to bring you the most exciting topics in the world of tech. Outside the office, I’m particularly passionate about motorsports and mountain biking.
