RevEng Posted October 7, 2010 Author Share Posted October 7, 2010 *Edit* Would it be possible for a game to have two seperate title screens, as long as they are stored in different banks? Also can you have sound with the title screens? RevEng, I have download and printed out your documentation and its very good. Thanks again for all the hard work that you put into this. I truly feel that we have not come even close to maxing out the potential of batari Basic programming for the 2600! -Disjaukifa Unfortunately it's not possible to have 2 different title screens, even if they're stored in 2 different banks. You do have some limited ability to change what graphic is being displayed, as shown in the animation example. Sound is definitely a possibility. You call the titlescreen drawing routine with a gosub, but otherwise it acts the same as a bB drawscreen command, so you can control sound just as you would in a game. Agreed on bB programming having even better days ahead of it. When batari gets around to coding a DPC+ kernel I'm positive you're going to see a lot of the compromises in the present bB kernels vanish. (blank lines, losing a missile for colors, etc) Quote Link to comment Share on other sites More sharing options...

(blank lines, losing a missile for colors, etc) Any idea (or rumors) about a release schedule? I wish I don't have to rewrite my whole game... For the moment I can't make the TSkernel flicker: Do you use a variable for it? I'm using a bit of the variable "a" as tag for flickering and the detection seems in conflict with it. Regards.

RevEng Posted October 7, 2010 Author Share Posted October 7, 2010 Any idea (or rumors) about a release schedule? I wish I don't have to rewrite my whole game... For the moment I can't make the TSkernel flicker: Do you use a variable for it? I'm using a bit of the variable "a" as tag for flickering and the detection seems in conflict with it. Regards. batari mentioned it once or twice, but I wouldn't count on it popping anytime soon - he has his hands full with other projects too. In any case, I'd expect you'd only need to tweak your existing game to get the benefits. To flicker the TSKernel, you could just alternate the gosub calls with drawscreen calls, like... main gosub titledrawscreen bank2 drawscreen rem insert some game logic here goto main But I think some of the minikernels that use flickerblinds might not perform correctly when you do that. The TSKernel tracks the frame with a temp variable that the bB kernel is likely to wipe. Quote Link to comment Share on other sites More sharing options...
abaudrand Posted October 7, 2010 Share Posted October 7, 2010 I thought the TSkernel include a drawscreen function. I'm stuck for the moment but I will do another attempt tommorow. (when I'm stuck on a problem, I let my brain compute it while sleeping). Quote Link to comment Share on other sites More sharing options...
RevEng Posted October 7, 2010 Author Share Posted October 7, 2010 The TSKernel uses the "gosub titledrawscreen" as its drawscreen. Quote Link to comment Share on other sites More sharing options...
disjaukifa Posted October 7, 2010 Share Posted October 7, 2010 The TSKernel uses the "gosub titledrawscreen" as its drawscreen. Not to ask an off-topic question but what is TSKernel? I've done a search and didn't see much? I know Random Terrain's website has a little info on kernels, but I only remember seeing players life, racing timer and titlescreen. What other kernels are there? -Disjaukifa Quote Link to comment Share on other sites More sharing options...
RevEng Posted October 7, 2010 Author Share Posted October 7, 2010 Not to ask an off-topic question but what is TSKernel? It's the Titlescreen Kernel, when I get tired of writing the name a bunch of times. I'm not sure what other kernels exist. Quote Link to comment Share on other sites More sharing options...

RevEng Posted October 8, 2010 Author Share Posted October 8, 2010 I knew that . . . . no I didn't . . . No frownie required - its not like I announced the name variation anywhere. I just started using it. But I won't object if anybody refers to it as TSKernel, TSK, the title thingee, or whatever. "The Titlescreen Kernel" is a bit much to type over and over again.

codyr783 Posted October 16, 2010 Share Posted October 16, 2010 Would it be possible to add some of these to your game itself? I was wanting to use the title for a horizon in the background. Quote Link to comment Share on other sites More sharing options...
yuppicide Posted October 16, 2010 Share Posted October 16, 2010 Interesting question cody.. I don't know ASM, so I don't know how Rev's code works, but let's say we have a TITLE only.. is it possible to move some sprites around while the title is being shown?

RevEng Posted October 17, 2010 Author Share Posted October 17, 2010 Well, it's not possible with the code as it is now. With some modification to the bB kernel, it's possible that one could have a "topminikernel" for stuff like sunrise displays. But in truth I'd like for such an interface to be official before I started modifying minikernels for it. Quote Link to comment Share on other sites More sharing options...

Sooner or later, you guys with brains are going to make it so every bB game will look so good and professional from start to finish that Atari 2600 gamers will weep with joy. They'll begin to wonder if Imagic or Activision started making Atari 2600 games again. Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted November 18, 2010 Share Posted November 18, 2010 OK, I've had it. I need help. Why won't this file make my game work? It compiles fine, but I get a blank screen. 48x1_1_image.txt Quote Link to comment Share on other sites More sharing options...
RevEng Posted November 18, 2010 Author Share Posted November 18, 2010 (edited) The file itself looks fine. Its set to be the first copy of the 48x1 data. Are you sure there isn't another file also set to be the first copy of 48x1? If not, post or PM all the files and I can see what I can do about it. [Edit - also, make sure the .bin file created was the right size] Edited November 18, 2010 by RevEng Quote Link to comment Share on other sites More sharing options...

Yes, I'm sure. [Edit - also, make sure the .bin file created was the right size] There's the problem, the file is only 6k. I hadn't noticed that before. It's supposed to be 16k. edit: when I remark it out with a semicolon, the game works fine. Quote Link to comment Share on other sites More sharing options...
RevEng Posted November 18, 2010 Author Share Posted November 18, 2010 There's the problem, the file is only 6k. I hadn't noticed that before. It's supposed to be 16k. Ok, so that's the start. Every once and a while bB spits out an incomplete binary due to a syntax error or similar issue, and except for the bad size its not obvious there was a problem. Just to make sure I wasn't missing anything, I copied your 48x1_1_image file into one of the examples and it compiled and displayed just fine. If you comment out the draw_48x1_1 line from titlescreen_layout.asm does everything compile fine? If so, maybe you've run out of space.

+atari2600land Posted November 18, 2010 Share Posted November 18, 2010 OK, I am officially an idiot. I found the source of the problem. It had to do with the older copy of the titlescreen kernel I had in there earlier. The code was pointing to the wrong file folder. Everything's fixed now.

RevEng Posted November 18, 2010 Author Share Posted November 18, 2010 No worries. I'm just glad to hear there's nothing for me to fix! Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted November 19, 2010 Share Posted November 19, 2010 Do we already know that "set debug cyclescore" does not work with the titlescreen kernel when the game is on the title screen? Because it doesn't. If we already knew that, never mind! Quote Link to comment Share on other sites More sharing options...
RevEng Posted November 19, 2010 Author Share Posted November 19, 2010 I knew, but it's a good point to explicitly state. If you're doing anything intensive in a titlescreen loop, it's probably a good idea to double-check you're not pushing more than the usual 262/312 scanline counts.

SuperNESFreak Posted December 31, 2010 Share Posted December 31, 2010 Hey, This is REALLY good. Hopefully I'll be able to implement it in my 'Going Dotty' game (PS. Thanks a lot for all the help with that!) I saw that the compiled BIN is 16kb, which seems kinda a lot for a titlescreen, whereas my game is only 2-3kb so far. Is there a lite version of this/how far can it be squeezed down? Also, why does the Robotron logo flicker? Just wondering. Looking awesome. Keep up the great work; you get awesome sauce.
