Space Seeker

Space Seeker
Developer: Taito Publisher: Taito Platform: Arcade (Taito System J) Released internationally: October 1981 This game has uncompiled source code. This game has unused enemies. This game has unused graphics.

It's Space Seeker! Join plucky space captain Chet Seeker in this genre-shifting, space-shooting action game, as he deletes temporary internet files and half-finished anime torrents from the hard drive of Taitooine!

Unused Graphics

Graphics for this odd winged enemy are loaded in the cockpit shooter sections, but it never appears anywhere.

This thing is loaded too, whatever it is. This is its only frame of animation.

Filler Text

Some uncompiled code appears as filler text. Unusually for an arcade game, the text is found in the graphics ROM! Code starts at 2580, and appears to be an early version of what appears at main CPU ROM address 202F (which makes fewer function calls):

;*  0(Y):COIN             

To do: Really an early version of the final code?

Note: this code snippet does not use Zilog assembler syntax, but the CPU is still a Z80. The POP instructions are all 16-bit pops, and PSW corresponds to af; in effect, the end of the code is, in Zilog syntax,

	pop	iy
	pop	ix
	pop	hl
	pop	de
	pop	bc
	pop	af
	ei
	ret
