MIRAI's MSX2 version just landed on Nintendo Switch

D4 Enterprise has released the 1987 MSX2 action RPG MIRAI for Nintendo Switch. The game joins the publisher's ongoing EGG Console series, which brings classic Japanese microcomputer games to modern hardware.

Originally developed by CreativeBrain, MIRAI is a sci-fi action RPG that splits its gameplay across six different planets. D4 Enterprise previously released the PC-8801mkIISR version of the game for Switch in May 2025. Today's release specifically brings the MSX2 edition to the Nintendo eShop. This gives players a chance to experience the game with the distinct color palette and audio hardware of the MSX standard.

The REINBOW Nebula

The game takes place in Universal Century 720. Humanity has abandoned a ruined Earth and attempted to migrate to the REINBOW Nebula. This new home consists of six wildly different planets governed by a central authority that is entirely hostile to human life. You play as a mysterious soldier who discovers an advanced armored suit and sets out to fight the planetary rulers.

Each planet operates as a two-part mission with distinct gameplay styles. The surface levels play like side-scrolling aerial shoot-'em-ups. You navigate through enemy fire and environmental hazards while managing your suit's energy systems. Once you locate an entrance to the underground, the perspective shifts. The game becomes a close-quarters action platformer focused on hand-to-hand combat.

Strict fuel management

Survival in the aerial sections relies entirely on strict resource management. Your armored suit constantly burns fuel while flying. If the tank hits empty, your health immediately starts draining until you die. You have to carefully route your flight paths between refueling stations to stay alive.

The game is notoriously difficult and actively punishes poor planning. Some stages remove refueling stations entirely. To survive these areas, you have to manually equip smaller, lower-power vernier thrusters before the level begins to conserve fuel. If you forget to swap your thrusters, you will simply run out of energy and die mid-flight.

Underground brawls

The underground sections drop the flight mechanics in favor of traditional platforming. You navigate brick-filled corridors and fight through waves of enemies to reach the boss encounters. These fights require you to find and exploit specific weak points on large mechanical enemies.

The game also includes brief top-down exploration segments. These areas add a third perspective to the mix. The UI retains the classic MSX2 aesthetic. A bulky status menu overlays the action to track your health, fuel, and equipped items.

The EGG Console project has become a steady pipeline for obscure Japanese computer games on the Switch. D4 Enterprise has spent the last few years digging through the catalogs of the MSX, PC-88, and PC-98 to resurrect titles that never saw an international release. Companies like Hamster focus on arcade history with their Arcade Archives line. D4 Enterprise handles the often-overlooked world of 1980s Japanese personal computers instead.

Like most EGG Console releases, the game costs $6.49 on the eShop. The wrapper provides modern save states and display options, but the ROM itself remains untouched. The manual and story text are still in Japanese, though the menus and UI elements use enough English to make the core action playable for import fans. If you have the patience to learn its brutal fuel economy, MIRAI is a fascinating look at how 1980s PC developers tried to cram three different genres into a single cartridge.
