Aero Fighters (SNES)

The SNES port of Aero Fighters is one of the rarest standard North American releases, produced in very limited quanitities.

Regional Differences
In the Japanese version there's a second loop once you beat the game once, in the North American version you go back to the title screen instead. Also, each loop had a different ending, which were combined into one for the North American release.

The Japanese version has two bad endings, which were triggered if you let one of the last bosses escape. These were removed for the North American version. However, the translation for these endings can be found inside the ROM of the North American version.
