R-Type DX: Music Encore features the ultimate mode, Ultimate Challenge, allowing players to battle through both titles seamlessly. For the first time, this mode includes a full soundtrack. Arcade-accurate stage themes have been newly implemented — including dedicated tracks for areas that originally shared music — enabling every stage to be played with the same musical structure as the arcade versions. Experience newly reconstructed sound created using authentic handheld hardware audio. The original R-Type and R-Type II are also included. In Classic mode, players can choose between monochrome and color versions, preserving the feel of the original release.
