Due to the amount of space reserved for graphics, all I have room for is a 36x36 pixel picture. So I played with the code and got a picture of a huge treasure chest in. Perhaps TIX can make it better than what I have now? Also, I only have room for 20 levels, not the 30 I was hoping for. ..bummer In my opinion the chest is more appropriate for a win screen ! I have squeezed my sinking sub into 36x36 stamp size.. I think it looks pretty good considering !

+atari2600land Posted September 24, 2019 Author Share Posted September 24, 2019 That's what I was working on. Do you want me to put this picture in the game over screen or the ending screen?

TIX Posted September 24, 2019 Share Posted September 24, 2019 The sinking sub goes definitely in the game over screen. Ending screen you mean when you complete the game right ?

To be honest I'd be very surprised if you had completely filled 4 graphics blocks. Remember that (assuming you're using a 16 line zone size) you can cut down graphics into 4*16 blocks, and if you've got a large graphic with lots of empty space then you can always split it into different parts.

If I put two 64x64 pictures in, it says I have -3000 bytes left. I'm using an 8 line zone size, but I don't see how that makes a difference.

+SmittyB Posted September 26, 2019 Share Posted September 26, 2019 Everything the 7800 draws is 1 zone tall (anything taller is actually drawn as separate pieces) so the smallest unit of graphics data you can have is 1 byte by 1 zone, or in your case 4 by 8 pixels. As everything is a zone tall, anything not a multiple of the zone size gets padded with zeroes so a 36*36 image is actually stored as a 36*40 image (9*5 of those small 4*8 units). If you had a 16 line zone size then it would be stored as a 36*48 image. If you were to take all of your graphics and cut them up into 8 line tall strips I imagine you would find that a lot of it is wasted space. What I meant to say before is that by identifying where that empty space is you can break up the graphics you import to make better use of ROM. It would mean that rather than say a single call to plotbanner you might have to make a few calls to plotsprite but it would be a way to squeeze in more graphics. 2 Quote Link to comment https://forums.atariage.com/topic/291619-gosub-wip/page/8/#findComment-4358322 Share on other sites More sharing options...

If your using 160B for your image I've found those images take up a huge amount of space. The ship on the intro in Arkanoid takes up 2.5 gfx blocks (of 3 in banks) just for that. From memory it's around 96x96 pixels (split into a left and right side). I'm going to have to do what SmittyB suggested to fit in some of the additional animations.

+atari2600land Posted September 27, 2019 Author Share Posted September 27, 2019 I was able to bump up the image size to 36x48 in case that helps. I still only have room for just 20 levels, though I don't see why. Most of the program is in dmahole 0 for some reason.

The compilation output should tell you if there is more space. For example: 339 bytes of ROM space left in DMA hole 0. 1485 bytes of ROM space left in DMA hole 1. 2048 bytes of ROM space left in DMA hole 2.

+atari2600land Posted September 28, 2019 Author Share Posted September 28, 2019 OK, here's the deal. The game will have 25 levels. I tinkered with the code a lot today. I don't have any room for more than 25 levels, but I do have room for an ending screen song, a boss song, and perhaps a bonus game song. I only have 105 bytes left in the main area, so I'll have to put the song data in DMAHOLE 0 where the most data free is. There's not much room in 32k for what I had originally planned, but it's close to what I wanted. gosub20190928.zip 1 Quote Link to comment https://forums.atariage.com/topic/291619-gosub-wip/page/8/#findComment-4359452 Share on other sites More sharing options...

bah Posted September 28, 2019 Share Posted September 28, 2019 Chris I like it. Plays well 32k I can put on most any original board, just needs a hex inverter like 4 k 2600 games. 48 k is not too hard but it won't fit on the base cartridge board.
