I actually started working on Mays program of the month, Joust, about three weeks ago. My goal was to update the program to a faster and more fluid MCODER version. Sadly, things havent gone so well. Pressed for time, I will leave you instead with my original take on this popular arcade from the 80s. This version, I created several, was pulled from one of my cassette tapes. Given this is a 9K program, loading it on a real ZX81 would take several minutes. Due to the magic of modern technology, you can now load this in seconds. Use the Z key to move left, the . key to move up and the N key to flap up. Since this is a ZX81, you cant hold down multiple keys simultaneously. This shouldnt be much of a problem as this BASIC program is pretty slow. Given the limitations of the ZX81, it doesnt look too bad. Overall, however, the game pretty much sucks.
Head on over to my ZX81 site to catch up on past programs of the month.
