tschak909 Posted April 22, 2021 Share Posted April 22, 2021 Somebody had asked for a giant fuji logo with rainbow, on Facebook... @ndary wrote one response, and I've written another: Source code here: https://github.com/tschak909/atari-logo You can also load it from #FujiNet at atari-apps.irata.online/Novelties/atari-logo.xex WIN_20210422_00_40_50_Pro.mp4 4 3 Quote Link to comment Share on other sites More sharing options...

ClausB Posted April 22, 2021 Share Posted April 22, 2021 There is also one in the 5200 BIOS. Is there one in the 1200XL OS too? 1 Quote Link to comment Share on other sites More sharing options...

tschak909 Posted April 22, 2021 Author Share Posted April 22, 2021 So I tightened up the rainbow a bit, made another version: Pasting both binaries here, and the source is of course on github, only difference is an additional DEX. atari-logo-2.xex For #FujiNet users, It's also on atari-apps in the same place as the other binary (atari-apps.irata.online in /Novelties/) So, tighter or looser rainbow? p.s. I did try to implement a variant that ran in MODE F, essentially reversing the screen to become a mask for COLOR2 changes below, so that the additional horizontal resolution could be capitalized on (and using a DLI at the bottom to stop the rainbow effect) ... it didn't improve the jaggies in either the fuji or the ATARI much at all, so it's been left on the cutting room floor...

TGB1718 Posted April 22, 2021 Share Posted April 22, 2021 I may be wrong, but wasn't the Atari the only computer at the time that could do this sort of thing with so little code ? Quote Link to comment Share on other sites More sharing options...

No, I believe you're right at least with the 8-bits. The Plus/4 can get quite close for the colours but needs twice as much code and a whacking great table of timing values since there's no WSYNC.

+Stephen Posted April 22, 2021 Share Posted April 22, 2021 Well, the 2600 could also do the effect with a few lines of code. 3 Quote Link to comment Share on other sites More sharing options...
Rybags Posted April 22, 2021 Share Posted April 22, 2021 Plus/4 I think is the only other 8-bit computer with close to the palette size (disregarding Apple IIgs which is closer to a 16-bit machine) Possibly with code optimization it could use a combo of wait loops on the raster count then set delays for the 2 successive badlines. But it can do FLI tricks also which can force attribute reads more often, allowing it to match the sort of thing we can have with RastaConverter. That one on GitHub - is the aspect ratio just out because a 4:3 output is being shown as 16:9 ? I had a Fuji worked out in Basic way back - from memory it used circle segments in the lower parts and I got it looking pretty good but the program is long lost now.

E474 Posted April 22, 2021 Share Posted April 22, 2021 I initially mis-read the topic title as a rainbow Fuji-Net logo, then wondered why it wasn't! Quote Link to comment Share on other sites More sharing options...
+CharlieChaplin Posted April 22, 2021 Share Posted April 22, 2021 tschak909's rainbow fuji logo looks like 16:9 (or 4:3 stretched to 16:9) and errmmm, I prefer the original 4:3 look of the 5200 rainbow fuji logo... ;-) 1 Quote Link to comment Share on other sites More sharing options...

+DrVenkman Posted April 22, 2021 Share Posted April 22, 2021 (edited) A little too wide and out of proportion for my taste. By contrast, here’s something @Stephen whipped up for @mytek’s most recent project. Edited April 22, 2021 by DrVenkman Formatting 5 Quote Link to comment Share on other sites More sharing options...

ascrnet Posted April 24, 2021 Share Posted April 24, 2021 First of all thanks for sharing the code on github ?, but it is strange your version of fuji. There is a game that has a very good one of course it doesn't use the whole screen. Regards 1 Quote Link to comment Share on other sites More sharing options...
tschak909 Posted April 24, 2021 Author Share Posted April 24, 2021 The graphic itself is a standard Micropainter image, that is, 160x192, 2 bits per pixel. The last four bytes of the palette data aren't used, and all the colors, save COLUBK are set to $0E. If someone has a better pic, then fold it in. -Thom Quote Link to comment Share on other sites More sharing options...
