TwinBee/Versions

Famicom
Developed by Konami in 1986. The disk system version is identical to the Famicom version (except for the copyright date, 1988). Instead of a green bell which gives you 3 ghost-like jet fighters that follow you, you get a flashing red bell which gives you 2 ghost-like jet fighters.

Game Boy Advance
Developed in 2004. Very similar to the Famicom version, however, the vertical resolution is further reduced, and the second player option has been removed (unless if you use Game Link cable or Wireless Adapter).

MSX
Developed by Konami in 1986. Has smoother graphics than Famicom version, but choppy scrolling.

Sharp X68000
Developed by Konami in 1988. The graphics are close to the arcade version, but the graphics has been "smashed" to fit the screen.
