I would like to inform You that there is a new arcade game for ZX-81 on URL: http://hooyprogram.republika.pl/ferengi_zx81.rar
The game is entitled "FERENGI"
and it's made by HOOY-PROGRAM & ANDRE*** in 2008. The archive contains:
1) "Read me" file with instruction
2) cover-arts for cassette
3) WAV files to record them on a cassette; there are two versions:
*full version* of "FERENGI" game for expanded ZX-81, Timex 1000 and for Timex 1500 (comps with 4 Kb of RAM or more)
and a version for unexpanded Timex 1000 (2Kb of RAM)
4) *.P files for ZX81/TS1000 emulators, also in 2 versions.
INSTRUCTION:
This game is a continuation of the classic ZX-81 game "Klingons".
This time Klingons were flying through space with a ship full of gold-pressed latinum for the Empire. Sadly (luckily for you 
) they crashed in an asteroid field and all the gold-pressed latinum bars are flying among the asteroids now. This is an opportunity for you. And you're Ferengi so you LOVE latinum. That's why you have to enter the asteroid field with your spaceship and collect as many latinum bars as you can, before more Klingons come here. Ferengi Rules of Acquisition tell you to do that even though the asteroid field is the most dangerous place for a spaceship. You must avoid the asteroids - they will make you a dead Ferengi for sure. Control panel of your ship: cursor keys - "5" and "8" (left/right).
Good luck, YOU UGLY ORANGE DWARF!!!!!!!
(I said "dwarf", not "Worf").
Yours faithfully,
YERZMYEY/HOOY-PROGRAM
