So I have the code back again to one bank of 32k. I read that to use a game on an Everdrive (which I am going to get), it should be in powers of 2, which 48 isn't. So I figured out how to change the size of c000, which is 48k, down to 32k, which is done by multiplying 32 * 1024, which gives a hexadecimal value of 8000, which I inserted, and it worked. Now...

I see a pattern arising here. My Mr. Celery episodes are 32k. And now that I am working on Mr. Ultra for Game Gear, I think I am just going to make it a 32k game as well. Although there are some differences. The Atari 2600  was made so long ago that in order to make a 32k game, you have to do a ton of bankswitching (8 banks in a 32k game.) With the G...

Mr. Ultra can jump over celery

Posted by atari2600land, 04 October 2015 · 60 views

Well, I finally got Mr. Ultra's second enemy in the second level. It took a long time to program it in, but in level 2, there's celery. And instead of walking, it jumps up and down in place. It isn't very big celery like my 2600 bB animation, just your basic celery with legs and feet. The outline for level 2 is still the same as level 1, I'm hoping to cha...

Mr. Ultra has music

Posted by atari2600land, 03 October 2015 · 67 views

Well, the guys at SMS Power! figured out what I was doing wrong, and now I can have music in my game. So I composed a short little tune for level 1. There is no music for the title screen yet, but I hope to compose some and put it in there now that I know how. Bank 00 has 48% free, so I have a ton of room for a simple song for the title screen. I'm just s...

So for the past two or so days, I've been trying to put music in the Game Gear game I'm making. Each and every time I try, I fail. I appealed to the SMS Power! forums (the ones who know all this stuff) for help, so I guess I'm in wait mode for this stupid thing. All I want is music, why does it have to be so HARD? I can do noise in the Odyssey 2 assembly...

Mr. Ultra can finish level 1.

Posted by atari2600land, 30 September 2015 · 82 views

I promised myself a break, but it didn't turn out that way. At least it wasn't more than a couple of hours of programming. I made the layout for level 1. It was hard. The game kept wanting to do stuff I didn't tell it to again (I hate when it disobeys me!), but it finally worked right. I also made the bananas wait off screen if Mr. Ultra stops and the ban...

Mr. Ultra can jump over enemies

Posted by atari2600land, 29 September 2015 · 67 views

I added a few enemies. I don't know why, but I spent the whole night last night fighting with the stupid thing to make it work right. Now I'm at a good stopping point now that I've got both enemies and a hole to jump over. The collision detection code broke, it wanted to say there was a collision after the bananas walked off screen, so I had to make new c...

Mr. Ultra can jump over holes now.

Posted by atari2600land, 28 September 2015 · 85 views

I added a hole for Mr. Ultra to jump over. However, Mr. Ultra can't stand on the edge of the hole because he'll fall in if he does. All level 1 does right now is loop the hole over and over again. I know I said I wanted to take a little break from it, but I just wanted to get a few more gameplay basics in before my break. If you've seen my Super Giuseppe...

Mr. Ultra can walk now

Posted by atari2600land, 27 September 2015 · 82 views

So I decided to make the title screen a little better by adding animation to Mr. Ultra so it seems like he's actually walking instead of just gliding along. I also made the cloud 16x8, but it's just two 8x8 sprites formed together. Anyway, I was asleep almost all day. I had to. I just was very sleepy for some reason. I wasn't sick or anything, just sleepy...

Mr. Ultra

Posted by atari2600land, 26 September 2015 · 105 views

So I decided to retry making a Game Gear game. Since random numbers are hard and I can't quite do them, I needed a game idea that didn't involve them. So I thought. Why not a platform game, like Mario or something? That doesn't involve random numbers. So I tried working on a Game Gear game again. I had trouble. For nearly three hours I fought with the thi...
