TwinBee/Versions

Famicom
Developed by Konami in 1986. The Famicom 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. Instead of a bell that gives you triple shot, you get a candy.

Game Boy Advance
Developed in 2004. Part of the 2nd batch of Famicom Mini series. It's a port of 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 have been "smashed" to fit the screen.
