Thexder/Versions

= Apple II =

Apple II GS
Ported to the Apple II GS by Synergistic Software, Inc. Published in the United States by Sierra On-Line in 1987. While the game could be played in a crippled form on the regular Apple II, the version was programmed to take advantage of the advanced graphics hardware of the Apple II GS which brings it on par with the look of the Commodore Amiga version.

Commodore Amiga
Ported to the Amiga by Synergistic Software, Inc. Published in the United States by Sierra On-Line in 1987. Distributed in the United Kingdom by Activision in 1989.

Famicom
Ported by Bits Laboratory and published in Japan by Square Co. in 1985. Takes the most liberties with the level layouts, and enemy appearances. The biggest difference of all is that Thexder's weapon is converted from a laser rifle to a particle gun. Thexder shoots small particles at the enemies, up to three on the screen at one time, and they can potentially miss. There is also no set Max Energy amount.

Fujitsu FM-7
Ported by Game Arts and published in October of 1985.

MSX
Ported by Compile. Published in Japan by Game Arts in 1986. Published in Europe by Eaglesoft in 1986. Compile could only fit the first 9 levels in the ROM. Level 16 is recreated in the MSX version's Level 10, and an "ending" screen was added before the game repeats itself. Some of the enemy energy distributions were also changed.
