Digimon: Virus Version - A Unique Fusion of Pokémon FireRed and Digimon Adventure

Digimon: Virus Version is not your typical Pokémon ROM hack. Developed by the talented ROM hacker known as KlausThorne, this game is a remarkable fusion of the beloved Pokémon FireRed and the iconic Digimon Adventure series. By delving into the intricacies of this game, players are immersed in a thrilling adventure that combines elements from both universes seamlessly.

Concept and Setting

Set in the aftermath of the events depicted in Digimon Adventure 2, Digimon: Virus Version introduces players to a Digital World that is teetering on the brink of chaos. As the Digital World gains popularity among enthusiasts, it becomes increasingly burdened and susceptible to disruptive incidents. To address this crisis, Professor Nebilim enlists the help of five agents, one of whom the player assumes the role of.

Gameplay Mechanics

The core objective of Digimon: Virus Version is to utilize the Digivice D-virus to capture rogue Digimon and restore order to the Digital World. Drawing inspiration from Pokémon FireRed, players navigate through a world populated by Digimon counterparts of the original Pokémon species. The game faithfully recreates characters, maps, and items from the Digimon Adventure series, providing an immersive experience for fans.

Players have the opportunity to capture Digimon and engage in strategic battles, akin to Pokémon gameplay. Through leveling up and evolution, Digimon can grow stronger, adding depth to the gameplay experience. However, unlike traditional Pokémon games, players assume the role of antagonists seeking to infect Digi-Cores with the D-Virus, posing a unique moral dilemma.


The narrative of Digimon: Virus Version unfolds against the backdrop of a Digital World in peril. Players embark on a quest to infiltrate the Digimon world as agents tasked with infecting Digi-Cores. The overarching goal is to harness the power of the D-Virus to potentially reshape the Digital World, presenting a stark departure from conventional Pokémon storylines.

Game Controls

Mastering the game controls is essential for navigating the Digital World effectively. Players can activate commands by clicking the screen, while directional movements are controlled using arrow keys. Additionally, the game incorporates familiar button mappings from Pokémon FireRed, such as A and B for actions, L and R for additional functions, and Start and Select for menu navigation.


Digimon: Virus Version stands as a testament to the creativity and ingenuity of ROM hacking enthusiasts. By seamlessly blending elements from Pokémon FireRed with the rich lore of the Digimon Adventure series, KlausThorne has crafted an enthralling gaming experience that appeals to fans of both franchises. Whether you're a seasoned Pokémon trainer or a Digimon aficionado, Digimon: Virus Version offers a unique journey into the heart of the Digital World, where choices carry consequences and adventures abound.
