Are there any D&D folks in the audience? Come on, you know who you are. Past or present doesn’t matter, just if you know what I’m talking about. Why, you ask? Because RMS, April’s program of the month, will use your ZX81 to build monsters. Any fledgling DM could then use these creatures in their latest campaign. Elves and humans will cringe at your originality and cruelty.
Input One, March’s program of the month, is a great example of the kind of simple and brute force programming of the 1980s. This was a time when computers had little memory and their users had to use simple BASIC programming to get things done. The alternative was to buy a cassette tape of programs that took minutes to load even short programs, assuming they loaded at all. For the rest of us, we either typed them in or wrote little programs like this.
At the one level, you can sum up most programs into three big groups: business, gaming, or educational. Most of my programs fit into one of these base categories. The standouts are generally the animation or demo programs that really have no distinct genre. Even those, however, I can lump into one of the big three without much effort. There are times when these categories get blurred and a program can fit into two or more categories. This month’s program is one of those.
As 2014 comes to a close, I wanted to end the year with an original program of the month. For December, that program is V Water Battle, an action game from 1984. For some reason, the title screen I created said designed instead of wrote but I did both. I was an odd duck in 1984. You use the “Z” and “.” keys to move. Use the “M” key to fire. The goal is to stop the ships from stealing the water. Miss them or get shot and its game over. Of course, they steal the water after each wave anyway to make it harder. Given that I haven’t beat it yet, the game is more difficult than it would seem. Let me know if you do!
Sorry, still no Joust. It’s not where I want it and I’ve spent July working on my novel instead. That isn't to say that I’m going to leave July without a program of the month. Instead I’ve pulled from my original site to bring you one of my favorite programs, Block £ Spear. In this game you'll find yourself at the wrong end of a knight’s spear. Fortunately, you have a shield and can easily deflect the spear by using the Z and . keys to raise or lower your shield. Sounds easy? You might be surprised.
Okay I haven’t finished my remake of Joust yet, nor did I want to wait until the last week of the month to get an article out. Instead, I offer you Monster Maker as June’s monthly program. It’s pretty straight forward and anti-climatic against the power of today’s programs. Once you load it, enter in five numbers and type your monster’s name. That’s it. The program will then display a nicely formatted monster description based on your input.
I actually started working on May’s 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 haven’t gone so well. Pressed for time, I will leave you instead with my original take on this popular arcade from the 80s.
For February, I give you Time, a simple landing game with a twist. Using the Z and . keys, you maneuver your craft to each successive landing pad. If you miss the landing, keep trying but be careful. Run out of time and it’s game over! How high of a score can you amass? A fair warning, Time isn’t always fair.
For November, I’m looking both forwards and backwards. Although I wrote SNUNCH in 1983, I added a corrected version to my first ZX81 web page in the ’90s. SNUNCH was my early attempt at writing a PAC-MAN like game. Note that I said like, not clone. My goal was to be inspired, not to copy. Sadly, it isn’t very good, even after I fixed some of its logic flaws. Despite its flaws, I still believed it had potential and I set about updating it using MCODER II. It is this improved SNUNCH ML version that I offer as November’s program of the month.
Well it is getting late in the month and I didn’t want to pull another last-minute update. To make things a bit interesting, I used Zed Ex on my Android tablet to enter in this month’s entry. More on that in a bit. Let me first introduce our deliciously short entry for May: Up-Cake. A fast and simple scrolling game that is easy to play and hard to lose at. My kind of game!
Late and last-minute, I present April’s program of the month Star Dodge. A decidedly simple game that requires you to dodge stars randomly placed on the screen. Can you get your Tie Fighter shaped ship, an inverse H, past the increasingly more dense stars? Give it a try to see.
In 1984, I moved that Summer from Italy back to the US. As I was Flipping through my old printouts, I ran across one that I had marked as the last program I completed In Italy. How cool is that? Seeing this, I just had to make Raider V my program of the month for March.
Another year, another month, and now another program to celebrate 2013. January’s program of the month is an old one: Hit Man. From 1983, Hit Man was my attempt at creating a wall dodging program and it is a tough one to play.
December is upon us and Thyime is the last program of the month for 2012. My how quick the year has passed. Thyime’s elements include moving, shooting, a break through wall, and a moving enemy. It does all this while remaining fast. Thyime provides a decent game to close out the year.
I couldn’t help it. I updated Bonkers using MCODER II to convert the BASIC code to Machine Language. This improved the speed of the game making improving its playability. If you haven’t played the 1985 version, play it first so you can appreciate the difference. If you have, now give the 2012 version a try. Better?
November’s program is Bonkers! and it may drive you crazy! Simply use the ZX81 cursor keys to move your X around the field, avoiding the O’s and their trails. Can you survive, or will you go Bonkers?
October’s program, PAC-MAN, may leave you a bit confused. Inspired by that iconic arcade game, this version has no graphics. It does have dots, cherries and ghosts. It doesn’t, however, have any pictures of those elements. Give it a try and you’ll see what I mean.
Wow, August flew by way faster than I expected! Here we are at the end and I finally got around to uploading the monthly program. This month’s program, PAC-MAN Video, is a bit different. Although I call it a game, it doesn’t really play like one. It is totally random with a slight nod to you. Skill isn't required, just give it a try.
I’m back to the basics for July’s program. Can Punch is a simply graphic game that will probably infuriate you more than entertain. Don’t believe me? Go try it and decide for yourself. The goal is punch the can thrown at you. Use Z to raise your fist high and . to lower it. A deceptively simple game mechanic that I dare you to master. I double dog dare you!
Yes, I know I’m late. June is almost over and I’m sure my adoring fan is up in arms. I do have one fan, right? In any case, I’m breaking tradition for June’s Program of the Month and posting a more modern program. Pole Dodge 2 is my revamped version of April’s program. Before I dig into the details, go play it. It’s real easy, just use the “Z” and “.” to bank left or right. No really, go play it. I think you’ll find it much more enjoyable this go round.
Jet Flyer is May's Program of the Month. Although a bit late, I believe it is a bit better than last month's and worth a quick try. The goal is to keep your jet on course by using the “Z” and “.” keys to bank right or left. It isn’t an overly hard game. You just need to keep the course indicator close to zero. I won’t say how close to avoid spoiling the fun.
Pole Dodge is April’s Program of the Month and it is an odd one. Partially odd because I typed it in back in February, and partly because the program just doesn’t play well. I know that doesn’t lend well for one to give it a try, but try it you should. Why? Because the premise isn’t bad. It is the execution that leaves a bit to be desired. Of course, I blame the slow hardware.
E.T. may not have been my best game ever, but it was an interesting exercise in 1985. Loosely, and I really mean loosely, based on the Atari 2600 game, E.T. follows the exploits of the title character as he tries to find his way home. Originally written in ZX81 BASIC, I revisited E.T. to better understand how to use MCODER II. I was ultimately successful in compiling it and getting it to run. If you are adventurous, you can compare it to original version, bugs and all. Instructions for E.T. are available off my old ZX81 website.
What's this, another version of Road Hog? Yep. This is January’s Program converted to machine code using MCoder II. I was surprised how easy it was.
Okay, I’ve been a fan of adventure games, and specifically Infocom games, for most of my life. I have fond memories of playing great games such as “Planet Fall” and “Zork” when I was in high school on my C64. However, even before playing those games, I was playing and writing games on my ZX81 using a very simple adventure engine.
