Canoeing on the moon

For a change of pace, I decided to work on "Can You Canoe?" for the Odyssey². It took a long time, way longer than I expected, because the alien kept not displaying correctly. Level 4 is on the moon. I decided to make it so that the enemies zigzag after level 3. So the swimming alien moves up and down accordingly. There will be a total of 6 levels. I don't know what to have happen after level 6, though. Perhaps just go through all the levels again and again until you die. I don't know

Scrolling where there is none

I'm having a bit of a problem here. I want the lines to get the visual effect that the game is moving forwards. Right now I have this: I need some more eyes to look at this. What do you think? I have three grids rapidly changing to create this effect. I was thinking along the lines of an ever-moving Battlezone type game where the Xs shoot at Os on the ground. If this is good enough I'll add some trees to move along with this.

Shooting some hoops

So I decided to take another stab at my Odyssey² basketball game I had given up on. I somehow made it work. And I added a few things: shot clock shooting arc bug fixed ball-possession sfx fixed Before I made this video, I didn't take into account whether or not the player was shooting was the shot clock is winding down. So if it gets to 0 when in the act of shooting, the ball would probably mysteriously not go into the basket and it will be a jump ball instead.

The Golden Q Quest (part 2)

I worked all day on this yesterday and I have it now: The first bank of "The Golden Q Quest" is (almost) finished. I had to make a few changes, like not use the standing man character when the guy stops. This was causing him to get forever stuck inside the pyramid walls. Second, I added the inside of the other two rooms. This is the room where the Ruby r is in. The third room contains a Silver s. Right now when you get all three treasures and exit the last room, it goes back to the beginn

Three little ghostsesses

...sitting on postesses. Well, not really. It was a song I was forced to sing in elementary school. I attempted to put in a third ghost in level 3. Turns out I did in fact have room for it...barely. I only have 8 bytes left in bank 0 (where floor 3 is stored.) What I need to do now is figure out the entrance and exit points of each room in the floor. I will do that tomorrow. It's good that I have 8 bytes left since I don't need to add anything else in the bank, just change around data.

Robot Ron in 2084

So someone made a controller "coupler" for the Odyssey 2. What this does is puts both controllers together with a piece of plastic. I guess so you can hold both of them like you would, say, an NES controller. So now a game like, say, Robotron 2084 would be a cinch for games that would benefit from such a thing. And that's what I'm doing. I'm making one of my "semi-ports". This won't be like the original Robotron 2084 because my plan is needing to shoot a certain number of enemies that pop u

Fighting with computers

I took a few more hours and actually made it so the game updates the score automatically when you win, not when you press o to start a new game. I tested it on a real Odyssey 2 and it works! The thing is, when you press reset the game resets all the scores. Also, if you've been using the game and go to the tic-tac-toe game, the scores gets wiped out as well. In this screenshot, X just won his second game. Man oh man, this was HARD to do. The computer would not give up without a fight.

Scrolling where there is none (part 3)

I've been working on what I have for X vs. O. I added a flying O that goes by. This is what you're shooting at. But the most troublesome part was making this okay on a real Odyssey 2 because the screen part where the score is kept crapping out on me and I had to make it stable. Now after about three hours of programming, my right hand hurts because i've been typing and working the mouse too much. I've been going to sleep later and later. Yesterday I fell asleep at about 2:30 a.m. But i

Scrolling where there is none (part 2)

I just spent three hours on this: Fortunately, I had the scrolling all done from a previous project I gave up on, I just needed to add a tree and the X. I need to change the colors of the ground (x's can't walk on water and trees don't grow from the top of the water neither). Since I'm sleepy I'll go to sleep now and come back and read any feedback in the morning.

X vs. O - the classic rivalry (part 3)

Well, it took a LOT longer than I anticipated but I finally got win detection in. I had to sacrifice the words "CEDAR GAMES" during the intro, though, so now it just looks like this: X is green and O is blue. If X wins, the grid turns green, and if O wins the grid turns blue. The grid turns red if there's a tie. I had to spend all my waking hours Sunday on this stupid thing without getting it done. So I had to go to sleep at some point. So I did. I woke up today and began w

I tried again.

So I was having horrible trouble getting the fireball to come when a specific amount of points was got. I programmed for a couple hours until I got something working on an Odyssey 2 emulator, but it didn't work on a real Odyssey 2. So I pulled an all-nighter trying to make the thing work on a real Odyssey 2. Finally, at 7:21 in the morning, I made it work. This bit of code worried me:     mov r0,#score_l        mov a,@r0         add a,#245     jnc rrrrr The four-digit score

UStupiPS

It's almost 5 p.m. and still waiting for my stupid mail to come. So I drew this, colored this, and even added some text to it. I don't expect it to be used for anything, it was just something to cure my boredom waiting for the stupid mail to come. I finished the second floor of the giant pyramid. I don't have enough room for three ghosts. Having just two is hard enough, so it's going to stay that way. I made a program to help me figure out the exit and entrances of the rooms.

The Golden Q Quest

This is that Venture clone for the Odyssey 2 I was talking about. I worked a lot on it these past few hours, and I have a couple of screenshots I want to show you. This is the title screen. If you press Action on the left controller, you use it to control the guy. If you press Action on the right controller, you use that to control him. This is the first level. Notice there's only three rooms. I want to have room for enemies in the game, so I only put three rooms in each leve

A better nose.

The nose I had in Nosehair fo Odyssey 2 looked, well, crappy. So I decided to try to see if I could change it. This result looks a lot better than what I had before I think. Along with some other changes, I think this game may be close to, if not completely, finished. I tried to attempt a better nosehair demon, but it's VERY hard to draw a person-line 8x8 pixel sprite. To design the nostril, I cut off the upper part of the arrow so only the lower half was showing, and placed it at

Tunnels of Terror (part 1)

After Jack and the Beanstalk has entered testing phases, people don't really seem to find any bugs with what I have. I've been working on another Odyssey² homebrew. Someone on the Videopac.nl forum mentioned Turmoil and how it might be a good fit for the Odyssey². So, I decided to see what I could do with it. This is day 4 of working on it and here is what I have so far. Right now it's an 8k game. I figured if I had four banks, why not use them? Man, that link is big. I wish Video

Jack and the beanstalk

So last Friday I started a new Odyssey 2 project: Jack and the Beanstalk. Jack needs to climb the beanstalk. Most of my time was spent trying to decide what rules I wanted to have in place. I went from Jack being able to fall off the beanstalk to forcing him to always stay on the beanstalk. I went from a little bird to a big bird and then back to a little bird. Beanstalk climbing isn't the only part of the game. If it was, it wouldn't be a very engaging game. There will also be a

Testing.

I spent most of last night finishing up my Robot Ron game. It's come to the point where I think it's finished. Now comes the testing/feedback part. I have a few testers to test the game for me and tell me how I did. The changes I made: each enemy is introduced in each wave until all four enemies are in. Then the game becomes a fight for survival as (with most Odyssey 2 games) you only have one life. added a game over screen. changed the numbered box enemies to more alien-look

Q version 25

I got tired of working on Pineapples, so I decided to work on my Q game. I don't know why, seeing as how it's not a very interesting game, at least it isn't to me. But I need to find things to do while I wait to die, so I decided to do this. I wish I could die now, but I can't. I thought to myself "What can I do to make the game longer?" So I decided to slow the game down. When I thought about it, the q was moving fast, like running. But you can't run a long distance without your legs hurti

My latest Odyssey 2 project.

Here is a link to a YouTube video of my latest Odyssey 2 "doodle". My, that is quite large. Too bad there's no way to shrink that. Anyway, today's work was adding a level intro. The umpire needs to collect the umbrellas while avoiding the jet planes (which are not present in the video.) The next time I work on this, I will attempt to make a second enemy for level 2. I will try to make a maximum of 5 jet planes zooming around the screen randomly. An interesting thing happ

Flies

Yesterday I decided to make a new Odyssey 2 game. I attempted to put three sprites on the screen moving randomly. In the end, I could only put one. So I decided to make it like my Atari 2600 game Fruit Fly Fun. This is what it looks like so far. I decided on white as the background color so the black fly would be easily visible. That and I can't think of another Odyssey 2 game with a white background. I've always wanted to make a game with a white background.

Two flies.

So I was going to put three flies in the game. But that was impossible since I couldn't make the third fly swattable even though the code I wrote should have made it do. So I decided to attempt two flies in the game. That worked. So I have an idea for the game. It seems pretty simple, but I don't know if it will work. I spent all morning and part of the afternoon on it. I got it working, but I don't know if it will be fun enough. I sent my idea ROM to the publisher of the game and we'l

X vs. O - the classic rivalry

From tic-tac-toe to the gridiron, x's and o's have always hated each other. Now you can step inside an X's shoes and experience what it's like to be an o hating x. Well, not NOW, I just started with the game. Yep, it's a new game I started work on for the Odyssey 2. I don't know what the game will be like, I just created this since I was really bored. What I want is an 8k game. In bank 3 (the first bank), I plan to put in an Easter egg - a tic-tac-toe game. In banks 2-0 will be the game its

X vs. O - the classic rivalry (part 2)

So I finally got it working after 6 hours. You can now input letters in the tic-tac-toe minigame. I have about 300 bytes left to check for wins. I had to move an awful lot of codes all over the place. I think I must have spent 4 hours moving around code in desparation trying to make the thing work. The left controller enters the X's and the right one does O's. Since the controlers have 8 directions to move the joystick and a button, that makes 9 possible inputs, which works perfectly

Xybort - level 2

Watch out for the airplanes flying from right to left. So I didn't have a very hard time with this, except for the making my code I wanted it to be easier working a couple days ago. I wanted to make the levels differing code at the end so it wasn't interfering with the code structure. But this proved to be a difficult task since it wasn't working on a real Odyssey 2. It wouldn't get past the title screen. But eventually I made it work. I added a boss which moves around horizontally. The nex

Xybort

I have decided to make a new Odyssey 2 game. It will be called Xybort. I have been playing around with the title screen trying to get it just right. That's all I've done so far, though. Perhaps tomorrow I will actually work on the in-game stuff now that the title screen is completed. In case you're wondering, that white x above the big X is a sparkle. It switches between an multiply sign and a plus sign very fast, creating an illusion of a sparkle. In case you're wondering what Xybort
