Sky Skipper

A player attacks a gorilla (arcade version)

In Sky Skipper, the player pilots a biplane through scrolling mazes to save animals caged by enemy gorillas. The player must drop bombs onto the gorillas which will temporarily knock them out and unlock the cages. Then, the player must swoop down to pick up the animals before the gorillas get up and lock the cages again. Flying into a gorilla or wall destroys the plane, resulting in the loss of one life. The plane's fuel gauge goes down while flying, and is replenished by picking up the animals. There are four stages in total, which are repeated on increased difficulty.[2]

In 1981, following Nintendo Co., Ltd.'s highly successful Donkey Kong, the company developed and released Sky Skipper in Japan in the same year.[3] It was designed by Genyo Takeda and Shigeru Miyamoto with assistance from the company Ikegami Tsushinki,[4] a company that helped Nintendo program many of their early arcade games.[5] The cabinets were produced in upright, cabaret, and cocktail variations[3][6] with cabinet artwork done by Miyamoto.[7][8] The game performed poorly in test markets in Japan and was not widely released.[4] Around a dozen cabinets were sent to Nintendo of America in Redmond for location tests,[4][8] but the game was poorly received there also and was never widely released.[8][9] Because of the poor reception, Nintendo converted the Sky Skipper cabinets into Popeye, released in 1982.[3][10][11] One of the ten North American cabinets escaped this fate and put in storage at Nintendo of America.[8][12]

Although the game was never widely released in North America, Parker Brothers negotiated for a license to publish a home version of the game for the Atari 2600 as part of its licensing deal for Popeye.[12][13] The port was naturally of lower production value than the arcade version.[14][13]

During E3 2018, Nintendo revealed the impending release of Sky Skipper on the Nintendo Switch eShop in July under the Arcade Archives series run by Hamster Corporation. The ROM image for the game had been copied from the board in the cabinet at Nintendo of America because it is the only known unmodified boardset.[9] According to Nintendo World Report, the rerelease may have taken years to come to fruition because of legal issues with Ikegami Tsushinki.[5]

Reviewing the Switch release, both Nintendo World Report and Nintendo Life said the game was enjoyable when playing for a high score, but it lacked variety.[5][15] Nintendo Life enjoyed "striking a balance between completing the levels quickly and plotting a route to maximise your point-scoring."[15] Nintendo World Report did not like how the game repeated the same few stages and felt as though the game was not finished. They also panned the stage graphics, calling them "extremely crude" compared to Donkey Kong.[5] Nintendo Life agreed in that the colors were garish in places and the environments were blocky, writing this: "The simple design and plain backgrounds ensure everything is easy to follow, but Sky Skipper certainly shows its age."[15] Both praised the extra options included with the Arcade Archives release.[5][15]

Having played the vintage arcade, Nintendo of America's gameplay tester Howard Philips called Sky Skipper a "confusing thematic mess"[4] akin to an LSD trip.[16]^:12:55

Atari HQ found the vintage Atari 2600 port to be average, with simple gameplay and unremarkable graphics and sound.[13]

The restored Sky Skipper cabinet on display in 2017

In the early 2000s, developer Factor 5 founder Julian Eggebrecht made a deal with Nintendo that if he was able to ship Star Wars Rogue Squadron II: Rogue Leader (2001) on schedule, he could borrow their Sky Skipper cabinet for his company's arcade. Factor 5 shipped Rogue Leader on time and so received the machine. Upon booting it up, they realized one of the ROM chips was dead. They reached out to Genyo Takeda who pulled the original files from Nintendo's archives, enabling Eggebrecht to repair the machine.[4]

In 2016, a group of arcade restoration enthusiasts started a project to build a restored Sky Skipper cabinet.[17] No complete cabinets were known to exist in private collections. There were only four boards owned by collectors which, although loaded with Popeye ROM images, were known to have been converted from Sky Skipper based on their serial numbers.[12][18] Sky Skipper ROM images had been distributed online in the past,[12] so the team was able to deconvert the boards and reload them with Sky Skipper ROM images.[4] They still needed information on the design and colors of the cabinet, so they contacted video game player Billy Mitchell to connect with Nintendo of America.[4] To their surprise, Nintendo explained that they still had a Sky Skipper cabinet,[4] and granted them access to examine it.[8] They spent several hours on site scanning and photographing the cabinet.[12] With the scans they took, and sourcing one of the four known boards, they were able to create a faithful recreation of the cabinet in Nintendo of America's archives.[18]
