Lunar Chase © 1992 Nintendo of America, Inc.
Canceled export version of "X [Model DMG-ECJ]".
This version titled Lunar Chase was completed by Dylan Cuthbert of Argonaut Games; however, Nintendo of America felt that the idea of a 3D first-person game on a handheld for children was too complicated, and (to his disappointment) cancelled its release. Cuthbert believed that a lack of interest from retailers was also to blame.
In a 2018 interview, Cuthbert admitted that he lost the source code for Lunar Chase and didn't think to make a backup copy at the time.
An official ROM image of the complete English translation of Lunar Chase was unearthed in the 2020 Nintendo data leak.
