Jetboot Jack Posted September 5, 2002 Share Posted September 5, 2002 Debro, TIP creates the same (albeit flickery) resoilution as ANTIC E not ANTIC F - the only way to get a colorful true 320 pixel horizontal resolution screen is to use sprite overlays... sTeVE Quote Link to comment Share on other sites More sharing options...
calamari Posted September 5, 2002 Share Posted September 5, 2002 Debro, the only way to get a colorful true 320 pixel horizontal resolution screen is to use sprite overlays... Well, kinda If you want 320x96 resolution with 32 colors you can mix Graphics 11 (PRIOR=$C0) lines with Graphics 8 (PRIOR=$00). This gives the familiar blank line in between. There are 16 colors all of one brightness (since Graphics 11 is that way), and then if you don't draw a dot, that gives you a background color based on the main color (if you've used Graphics 8 you know what I mean here). Also, each color affects 4 horizontal pixels, so in reality you get 80x96 color resolution, and 320x96 drawing resolution. I tried converting some pictures to this format, and the results didn't look good, at least to me.. but it is possible to be useful with a clever artist, I suppose. You could also regain 320x192 resolution by drawing a second 320x96 screen and bumping it down a line, although this will flicker slightly like the archway demo. calamari Quote Link to comment Share on other sites More sharing options...

Heaven/TQA Posted September 5, 2002 Author Share Posted September 5, 2002 these gfx mixing facilities of the atari computer line was the "core" of my love to atari.... antic, gtia makes it possible...same spirit lives on in the copper-list of the famous amiga computer line... hve Quote Link to comment Share on other sites More sharing options...
calamari Posted September 6, 2002 Share Posted September 6, 2002 Can you post a demo picture of that mode - its sounds weird - but fun Okay here you go.. This is not from the emulator, but it is close to what you could expect. I tried converting the lake & archway but they were too ugly. You'd have to do something like that from hand. This image represents the 320x192x32 mode so there are no interlace lines but there would be a slight flicker. calamari Quote Link to comment Share on other sites More sharing options...

calamari Posted September 6, 2002 Share Posted September 6, 2002 Thanks! I just programmed the BMP convertor for it so I've implemented it . It turned out to look pretty close to the example. Here is the convertor, pics, ROM, and 5200bas program: http://www.azstarnet.com/~jeffryj/toystory.zip calamari Quote Link to comment Share on other sites More sharing options...
Jet Posted September 6, 2002 Share Posted September 6, 2002 WOW!! Thank you Calamari~ You ROCK!! Im grabbing it now. This is TOO COOL! Calamari, do you write with any other code? Have you ever tried WDL? or is there any VB in your background? Just wondering~ always~ Quote Link to comment Share on other sites More sharing options...
calamari Posted September 6, 2002 Share Posted September 6, 2002 Wow, good question, let's see what I can remember. I started off in GW-BASIC around 1987. I got Microsoft QuickBasic Extended 7.0 in 1989. Somewhere in this time I messed with C Robots a bit. In 1994 I started programming in assembly language using A86. I think my first HTML was in '95 or '96. Did some Pirch PIL scripting around here. In 1997 I started messing with 6502 and Atari 5200 programming. A coworker got me interested in esoteric languages in 1999, so I messed with BrainF***, and wrote Numberix in early 2000. I took a C class and also started working on a BF Basic compiler. Also took an ASM class so I became familiar with TASM. Wrote Hanoi Love and Spaghetti in 2001. As far as VB, I've written a few programs with it since 1999, enough to get kinda familar with it. Right now I'm working on 5200BAS and a couple games, and am taking a Data Structures course that is making me remember C again calamari Quote Link to comment Share on other sites More sharing options...
calamari Posted September 7, 2002 Share Posted September 7, 2002 Okay, I figured out the problem with my programs on the real system. The answer is explained here: http://www.atariarchives.org/dere/chapt05.php#H5_2 When I added the STA WSYNC (or in 5200BAS, WSYNC=A) the weird artifacts cleared right up. There were a couple other problems I was concerned with too: In Atari800 the flickering is noticeable and there is a weird black interference line that seems to move around. I'm happy to report that on the real system the flickering is not noticeable at all, and there is no weird line that moves around. So the images look great! I've deleted lake.zip because the 80x192 screen looks better, so I made a new 80x192 version of the lake and put it in with archway.zip. Both remaining zips have been updated with the WSYNC fix and are available for download: http://www.azstarnet.com/~jeffryj/archway.zip http://www.azstarnet.com/~jeffryj/toystory.zip Have fun, calamari Quote Link to comment Share on other sites More sharing options...
Sheddy Posted September 7, 2002 Share Posted September 7, 2002 Calamari, First guess to what the problems are: I had problems similar with Atari800 flickering and strange interference line too on my stuff. For mine it was the refresh speed of the monitor - it must be put in a 60hz mode (for NTSC), or it will not match the emulator's atari refresh speed and get out of sync on the screen drawing. (You need to set the vertical sync option on the emulator too, but I could never get version 2.5c to work right even then.) Also it seems to require a bit of luck with your PC setup as to whether it'll work right (video card, proc speed, etc) Must dash. Want to try your pics out and the Barbarian demo on the sprite topic.... Quote Link to comment Share on other sites More sharing options...
Sheddy Posted September 7, 2002 Share Posted September 7, 2002 if you give me the source picture i pass it over to fox... problem could be that the source will be XASM... hve OK, Heaven, let's see how this could look in TIP! Please pass to fox. I need to get into XASM anyway, so this will be a good excuse - The latest ATASM has changed how .includes work which I haven't got to work with relative filenames yet ( .folderfile or ..folderfile etc.) It has picked up some nice new features for cart coders though Thanks, Chris Edit: forget the part about relative filenames, that does work...it just does not accept a file name as part of a full path...ie %1 in .bat files won't work.

calamari Posted September 8, 2002 Share Posted September 8, 2002 Okay I've been tinkering again. I was thinking about how to get more colors with the 320x192 resolution, and I think I'm getting closer.. My new routine mixes 320x96x2 with 80x96x256 to give 320x96x"512". I doubt that it really produces that many colors, but that's what the math shows. Here is the .zip file: http://www.azstarnet.com/~jeffryj/archway2.zip I am thinking about mixing the CIF 80x192x256 with a 320x192x2 screen for 320x192x512 but the flicker might be too bad, it's already possible to see a little flicker with this one. calamari Quote Link to comment Share on other sites More sharing options...
Atari-Jess Posted September 9, 2002 Share Posted September 9, 2002 i have a question, downloaded the numen demo and firstly, wow, i crapped my pants and so did a bunch of my friends who were shocked only by the fact that the age of the hardware running it is as old as it is. (and myself for many more reasons) but i have to ask, was what i was watching, actual code displaying everything including the engine and levels, or was i just watchins a large movie that had been recorded before on another system running the actual engine and then the recording turned into some movie format and run on my 8bit (emulator, since i dont have that much ram ) thanks for taking the time to read this post, especially if you have answered it many a time before Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted September 9, 2002 Author Share Posted September 9, 2002 taquart never releases "movies" or "prerendered" stuff... start numen and then press f8 to enter the monitor... and you see by yourself... heaven Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted September 9, 2002 Author Share Posted September 9, 2002 and before i my harddisk died i had a vector only demo where you could walk around in the 3d scene... so it is not prerendered... if we would prerender the stuff why should then some of the effects not run at 60 fps??? depacking in realtime of 2600 bytes (VRAM) should be no problem... hve Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted September 13, 2002 Author Share Posted September 13, 2002 Chris, check your email... you should have the TIP stuff for space harrier. cheers, karolj Quote Link to comment Share on other sites More sharing options...
Sheddy Posted September 18, 2002 Share Posted September 18, 2002 Fox and the other Taquart members have been kind enough to let me pass on their color editor for TIP mode and some example source code for displaying the TIP picture (in XASM form). Their TIP conversion of the space harrier title page has come out pretty good too (check out shtitle.xex) What nice guys Thanks! sh_tip.zip coloreditor.zip Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted September 19, 2002 Author Share Posted September 19, 2002 we are all brothers and atari maniacs... why the hell are we doing senso 7800 dx, time pilot, numen, all the 2600 homebrews, space harrier, chatting @ atariage? simple answer... because we LOVE Atari... even now under infogrames flag... (but the stuntman chick at the games convention in leipzig was not to bad imho... ) hve ps. mental combat for 2600 was featured in PC Action, one of the bigger print pc game magazines in germany...(not yet in the stores...as we are getting the stuff 1-2 weeks before the "normal" consumer...). the limited edition box is brilliant...
