The boxed release is available now through online retailers and on the high street, aimed at collectors and players interested in Sunsoft's retro catalog.
The compilation gathers Aero the Acro-Bat (1993) and Aero the Acro-Bat 2 (1994), alongside a Game Boy Advance port listed as Aero the Acro-Bat: Rascal Rival Revenge, and the spin-off Zero the Kamikaze Squirrel (1994).
In addition to those mascot platformers, the set includes two Super Famicom-only originals now presented in localized form for Western audiences for the first time.
Those Super Famicom entries are Deae Tonosama: Appare Ichiban (1995), released in the West as Feudal Bros., and Shounen Ninja Sasuke (1995), localized here as Justice Ninja Casey.
Deae Tonosama is a top-down beat em up notable for its eccentric premise and unusual enemy roster; observers have described the title as uneven and often poorly executed, yet its offbeat design has earned it a cult appeal among retro collectors.
Justice Ninja Casey is a 2D brawler that follows a young ninja on a mission to rescue a kidnapped princess, distinguished by colorful character designs and a straightforward, repetitive brawler structure.
Sunsoft, the veteran studio behind these releases, has been recognized for several notable 16-bit era properties, and this compilation packages a mix of mainstream franchise entries and rarer regional releases.
The presence of two Super Famicom-only games localized for Western players is likely to be the primary draw for completionists and physical media collectors.
Aero The Acro-Bat Legacy + Sunsoft Lost Gems is sold as a physical product for PS5 and Nintendo Switch.
Retail packaging and availability vary by region; consumers should check local retailers and online shops for stock and regional compatibility.
For Nintendo Switch owners, this release provides a boxed alternative to digital re-releases typically found on the eShop, although this compilation is being promoted as a physical retail product at launch.
For developers, publishers, and retro gaming audiences, the compilation underlines continued commercial interest in curated physical reissues of 16-bit era catalogs, blending familiar mascot platformers with obscure regional curiosities in a single release.
