Juno Second


Guest

1,081 views

I have produced another Juno First kernel demo which is attached to this message. This mockup shows the aliens at fixed positions, and you can fire the ships laser. This demo is basically just to check that there is enough time to display the scrolling background and reposition the aliens in a 1 Line Kernel (1LK). The background lines actually skip over the repositioning lines which makes it a bit jerky, but this will be fixed later.post-3859-1092030094_thumb.jpgThe next step will basically require a complete kernel rewrite. At the moment, the sprite repositioning happens on fixed screen lines. However, this will need to change to a system with dynamic repositioning if the aliens are going to move smoothly. At the same time, I also want to incorporate Manuel's excellent flickersort routine to allow more than one alien to be shown on the same screen lines (with flickering). Finally, I need to include the missiles for the aliens shots, and there isn't time in the current kernel. It is going to be tough to do all this and still keep the 1LK! The current plan for the game sprites is as follows:Player 0 - Ship & Laser BeamPlayer 1 - Aliens (Flickered)Missile 0 - Alien Bullet 0Missile 1 - Alien Bullet 1Ball - Alien Bullet 2PF Background = Moving LinesEDIT: As noted in the comments, I have got a bit stuck with the PoP sprites as the artist seems to have disappeared. I will be very grateful for any help with this, as the game will not progress further otherwise. So far, I only have the following walking sequence:EDIT2: Nathan produced a cool logo for Juno First. It looks best using the Phosphorescent option in z26 or Stella: pescoman_v96.zipChris

Good luck with the kernel rewrite, Chris. One of these days I'm going to download MAME so I can understand the games people are doing.

Thanks - I think I have the new kernel worked out on paper, but I still need to implement it. You should definitely download MAME - it would only take a few minutes to install and you would have access to a huge library of classic arcade games!

Yeah, I'm surprised you've never used MAME. I've been using it since before it was called MAME...

 

Though I'd probably download ROMs from Bittorrent or something, where you can probably find all in one big archive (which I think is bigger than 10 GB now)

Never? Nah, just not in a while. I played MAME quite a bit in the late 90's. Since I started collecting Atari and other consoles, I've owned more games than I have time to play and emulation has been low priority. Now I have a reason to get MAME again. To keep up with others' homebrews. Thanks for the links, Chris.

This is cool and all, but what about PoP?

 

I haven't given up on PoP, but there are two things that are keeping me from making progress:

  1. The guy who was doing the sprites seems to have disappeared, and it won't be much of a game unless he comes back or I can find a replacement.
  2. I started a new project at work which is keeping me very busy at the moment. Doing some little mockups is a way of keeping programming without taking up too much time.

Thanks (and if you feel like doing some sprites then let me know ;))

 

Well, I still owe Manuel some explosions right now, but after that I could do some stuff for Juno First. ;)

 

Or did you mean PoP? :)

Thanks - you will be relieved to know that I was talking about Juno First. There is no hurry though as I am rather snowed under at the moment with other projects.

 

I haven't decided what to do about PoP yet - I am still hoping that Juston will reappear as he did a great job on the initial batch of sprites.

Whew! :)

 

(I still think PoP would be a great game, but it seems like an absolutely massive amount of work.)

I met a guy on Myspace that might be the type of guy to help out. I'll see what he thinks.

Thanks - any help that I can get with this will be appreciated. It is definitely beyond my abilities to generate these sprites. I have attached the current frames to the blog entry above.

Those look great! Are you planning to include all of the frames from the original? (I have them on my computer, and it looks like there are around 220.)

 

I just agreed to do some graphics for another game, but maybe after that one (and Juno First) I could help out some with PoP. But it'd be great if Juston could continue, he's got a really good start.

There are indeed around 220 sprites in the original PC game. I have attached a file kid.zip (which I think Thomas created) containing the PC game sprites. However, I probably won't need to include them all in the 2600 version. In particular, drinking the potion and picking up the sword can be removed, and the rest can probably be simplifed. I am still hoping that Juston will continue, but I haven't heard from him in a while - the initial animation that he produced is indeed a very good start. Anyway, if you feel like doing any sprites for this game then I will be very grateful, though I know it will be a huge undertaking.
