to turn an existing copy of Dragon's Lair into a Space Ace game. Early version #1 production units of the dedicated Space Ace game were actually issued in Dragon's Lair style cabinets. The latter version #2 dedicated Space Ace units came in a different, inverted style cabinet. The conversion kit included the Space Ace laserdisc, new EPROMs containing the game program, an additional circuit board to add the skill level buttons, and replacement artwork for the cabinet. The game originally used the Pioneer LD-V1000 or PR-7820 laserdisc players, but an adaptor kit now exists to allow Sony LDP series players to be used as replacements if the original player is no longer functional. Ports Numerous versions of Space Ace were created for home computers and game systems, most of which attempted to mimic the arcade version's lushly animated hand-drawn footage, with varying degrees of success. Along with the floppy disk-based versions for Amiga, Apple IIGS, Atari ST, MS-DOS and Macintosh, ReadySoft issued a CD-ROM version featuring downsampled video for MS-DOS and Macintosh which preserved almost all of the original laserdisc content. A sequel, Space Ace II: Borf's Revenge, was created and shipped on floppy disk for the aforementioned computer platforms mixing new animation with scenes from the original game that were left out of the previous version due to large file sizes. In 1991, Leland Corporation released a slightly updated version of Space Ace in the form of a conversion kit for the then recently released Dragon's Lair II: Time Warp. The updated version added more complicated moves (including diagonal moves), and dropped the easier skill levels, meaning only the "Ace" (difficult) level could be played. In 1993, Space Ace was released for the Philips CD-i (Compact Disc Interactive). It was later released on the Sega CD in 1994. Space Ace was also released for the SNES by Absolute Entertainment in 1994. However, since a SNES cartridge has limited storage, it ended up being a top-down perspective action game with levels based on the scenes from the original. In order to see the credits, the player must get an "Ace" rank on every level, meaning that they must have near-perfect accuracy and collect all the disks found throughout the game. The Dragon's Lair Deluxe Pack released by Digital Leisure in 1997 featured Space Ace along with both arcade Dragon's Lair games. They also released a version of Space Ace on
