F-22 is an unlicensed shoot-em-up featuring what might be some of the worst cutscene graphics to ever appear in an NES game. There's also music from Star Wars in some of the later levels. That's nice.

Unused Graphics

While seemingly original at first glance, F-22 is actually a massive hack of the Famicom version of 1943. F-22 uses a CHR chip for graphics data, while 1943 stored its sprites in PRG; as a result of this, almost all of 1943's graphics are still present in F-22's PRG data, completely unused.

Additionally, the Shanghai Paradise logo is present in the CHR data; this is presumably used in the original release of the game, but said version has yet to be found.

Graphics for an exit option are present in the CHR bank used by the options screen. This was likely scrapped as the menu can simply be left by pressing Start.

Credits Screen

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: Screen is definitely unused in the Waixing version; is it used in any alternate variants?

If byte #1C04D (of which its initial byte varies depending on the version) is changed to 0A, a credits screen can be seen. When translated to English, it reads "Programː Xi Feng, Yan Rong [;] Artistː Pepe".

Version Differences

There are 2 versions of the game, the initial release by Inventor, and a later release by Waixing. The Waixing release changes the title screen, removes the cutscenes and ending, and reduces the number of levels from 16 to 3.

A minor hack of the Inventor release published by Power Joy which replaces the title screen and changes the background color used in menus and cutscenes from black to gray.
