Flying Tiger, existing in at least two sets (Set 1 and Set 2), presents an intriguing case of revisions or alternate releases within the same game. These variations might involve different graphics, gameplay tweaks, or even entirely distinct level designs. The differences between Set 1 and Set 2 are currently unknown, needing further research into ROM dumps or arcade game databases to make meaningful comparisons.  The original developers and the specifics of their development process are not readily available.
