I think "ne" is the newest one, based on the order in the PS2 version.
Compared to the parent set "fantzone", there are some differences, such as invincibility time at the beginning of the game, "MAP" on the left side of the base radar, and all remaining aircraft are counted when the game is cleared, in addition to the possibility of continue.
In addition, "no" does not have invincibility time.
By the way, this is additional information, but the Astro City Mini version looks the same as the "no" version, but it has a demo sound.
I think this is a cheat, not a separate set, but I don't know if it is true or not.
