D4 Enterprise continues to release retro PC-9801 and MSX2 titles through its EGG Console line on Nintendo Switch and Steam, with four new titles added between June and July 2026.
D4 Enterprise has been steadily expanding its EGG Console retro game service across 2026, releasing titles originally from Japanese PC platforms of the 1980s and 1990s. The company brought Marchen Veil II PC-9801 to the Nintendo eShop as the 102nd EGG Console title on June 4, 2026. That action RPG, originally from System Sacom in 1986, alternates between visual story scenes and four-directional scrolling action, with enhanced speed, enemy attacks, and map size over the original.
Later in June, D4 Enterprise released EGG Console First Queen IV PC-9801 as the 105th title on June 25. That real-time simulation, originally from Kure Software Koubou in 1994, features the series' Gocha Character System, new dual-unit controls, fatigue mechanics, and mercenary hiring. The company also announced on June 2 that Relics MSX2, a 1986 action-adventure from Bothtec, would join the EGG Console line on Steam on June 19 for 1,200 yen. The Steam version includes a Scene Select mode and a Gallery mode for viewing the original manual and package art.
On July 2, D4 Enterprise released Relics for the Nintendo Switch as the 106th EGG Console title. That version also includes a Scene Select mode and a Gallery mode. The original MSX2 game, from Booster Technology in 1986, features a Spirit Ride possession system that lets the protagonist take over defeated enemies' bodies, determining attack methods, stamina, and character reactions. Across these releases, D4 Enterprise is bringing niche Japanese PC games from the 1980s and 1990s to modern platforms with added convenience features.

D4 Enterprise announced on June 2, 2026, that Bothtec's 1986 action-adventure game "Relics MSX2" will be released on Steam as part of the EGG Console line on June 19, 2026, for 1,200 yen. The game is set in a mysterious ruin that rose from the sea, where the player controls a protagonist who exists as a spiritual entity with no clear objective. The core mechanic is the "Spirit Ride" possession system, which lets the protagonist take over the bodies of defeated enemies. The possessed body determines attack methods, stamina, and how other characters react, making body choice a strategic element. The original game was noted for its sci-fi character designs, detailed humanoid animations, and effective use of sound effects such as wave sounds, which created a cinematic experience for its time. The EGG Console version includes a Scene Select mode for jumping to specific scenes, final battles, and endings, plus a Gallery mode for viewing the original manual and package art.
