-Mr Qwak has released Retro Racing for iOS, which is similar to the developer's previous Amiga racing games Nitro and ATR: All Terrain Racing.
-West Coast Software released D/Generation HD on Steam, which would be improved if the full-height walls disappeared at the moment you enter a room.
Also, Cope-Com released Battle Squadron ONE on iOS but it has since disappeared from the iTunes App Store
