Expansion Pak commercially. Nintendo was reluctant, expecting the technology to be reserved solely for hardware peripherals. However, after Iguana Entertainment also wanted to use the Expansion Pak to achieve a higher display resolution for Turok 2: Seeds of Evil, Factor 5 was given the green light. Ultimately, Rogue Squadron was made to run on a standard Nintendo 64 but the Expansion Pak increases its resolution from 320 × 240 to 640 × 480. Lucasfilm was hesitant to grant access to the Star Wars library of sound effects to Factor 5 sound designer Rudolph Stember.

Rogue Squadron was the first game released under this agreement. To promote the release of the game, Mark Hamill, the actor who played Luke Skywalker in the Star Wars films, visited the Mattel Children's Hospital in Los Angeles to play the game with patients in a Starlight Children's Foundation's Fun Center.

GamePro remarked that Rogue Squadron "enhanced the flight model with true pitch, roll, and bank mechanics". IGN praised its inclusion of "upgrades, more enemies, better sound, and stunning second-generation graphics". The Nintendo 64 version received mostly positive reviews, and received an aggregate score of 85 percent from both GameRankings and Metacritic. GamePro named it one of
