Irgendwer Posted March 27, 2006 Share Posted March 27, 2006 (edited) new g2f (25.03.2006) http://g2f.atari8.info p.s. all g2f files from Forever 7 (with Victory gfx) -> release 3.8.4.4 (26.03.2006) Thank you the fixed version. Now I can finalize my picture. (Result will be posted here soon.) I still found some minor bugs, but they aren't so bad that they prevent the completion of my artwork. Let me know if you like a report. Just one question: Since you haven't changed the limit in the new version, the maximum change count for a 32-byte-width screen IS 4?

Dracon Posted March 27, 2006 Share Posted March 27, 2006 I still found some minor bugs, but they aren't so bad that they prevent the completion of my artwork. Let me know if you like a report. Tebe is likely to know it (still) so go on with it. Besides, do you know "CUNEIFORM" (a C64 charset editor on PC, similar to G2F in idea) ? It's here. And it isn't under development, but wouldn't it be cool to analyse this and take the best things to G2F? What do you know? Any reasonable suggestion? Well at least it may come some new idea within G2F, I guess... Quote Link to comment Share on other sites More sharing options...

_Fandal_ Posted March 29, 2006 Share Posted March 29, 2006 (edited) Result will be posted here soon. Have fun. Very nice! But: did you try it on real HW? There's a little bit destroyed picture on my PAL machine. The top and the bottom are running out of TV screen... Can some G2F expert check the source file for possible errors? F.

Irgendwer Posted March 29, 2006 Share Posted March 29, 2006 disable last row and it's OK I've tested it only on A800. How this can happen? I thought when the 'Check'- functions reports no errors, the image is ok?!? What is the reason for the problem? Quote Link to comment Share on other sites More sharing options...
Dracon Posted March 29, 2006 Share Posted March 29, 2006 (edited) I thought when the 'Check'- functions reports no errors, the image is ok?!? What is the reason for the problem? I guess you could have used too many screenlines. They all could be OK as regards color changes, etc. but ANTIC doesn't handle too many screenlines to display, I think. So that's what causes trouble and it's not detected in check-option at the same time... This may also lead to conclusion that there should be limits on available amount of height in G2F to prevent such bug....

Rybags Posted March 29, 2006 Share Posted March 29, 2006 Running any 1/2 colour-clock mode on line 239 will cause warping. Other modes should be fine. Quote Link to comment Share on other sites More sharing options...
emkay Posted March 29, 2006 Author Share Posted March 29, 2006 Running any 1/2 colour-clock mode on line 239 will cause warping. Other modes should be fine. Yes... Because 240 lines definatly can be displayed. I even forgot about this 1/2 colour mode issue when we created the "first" Nazgul Intro. The last line set to mode 2 and the screen rolled over.

Rybags Posted March 30, 2006 Share Posted March 30, 2006 Additional: I just tested, same applies to GTIA modes. Strangely, my capture card reproduces the warping in the exact way that it happens on a TV. So, it must be some sort of bug in ANTIC. Putting it into widescreen DMA even makes my capture card do a "vertical hold roll" effect. Quote Link to comment Share on other sites More sharing options...

Ok, but what I did not understand is, that my former picture 'Tribute to Thyness' uses the same displayline count and seems to make no problems, since 'fandal' included this image to his pages without any complain and AFAIK tested this also on a real machine!?! I like to have an explanation which enables me to overhaul the Crises image by using the maxium capabilities possible... (Maybe to make it more 'Tribute to Thyness' compatible than just removing the lowest line which IMHO destroys the impression of the picture....) Could it be that it depends on the basic image character (1x1 / 2x1)??? (Eventually we discovered a new behaviour of the machine that even the A800 developers not were aware of?) Questions, questions... Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 30, 2006 Share Posted March 30, 2006 Like I said before, it's a 1/2 colour clock mode on line 239 which will cause the warping. ie- BASIC modes 0 and 8. And including GTIA variants (9 to 11). Any other mode if fine. AFAIK, no emulator replicates the behaviour. Probably because it has no good use.

I thought you check all images on real hardware before publishing them on your page. ) Think, I have to overwork this image too.

Time to reactivate my real machine and to perform some tests by myself. Stay tuned for updated versions... Well, you're right, I'm testing every piece of stuff published on my site. The problem is, that my real Atari HW is connected to PC TV card. And sometimes I get a "vertical hold roll" effect while TV set displays the same screen corretly. Unfortunately, I didn't test "Tribute to Thyness" on TV set as I thought there's just another problem with my TV card. "Crises" could be the same story. I just had enough appetite for switching antena output to TV set. And the rest you know. F. Quote Link to comment Share on other sites More sharing options...
Irgendwer Posted April 1, 2006 Share Posted April 1, 2006 ...Well, you're right, I'm testing every piece of stuff published on my site.

Unfortunately, I didn't test "Tribute to Thyness" on TV set as I thought there's just another problem with my TV card. "Crises" could be the same story. I just had enough appetite for switching antena output to TV set. And the rest you know. ... Thank you for the explanation. I did some tests on the real thing and found some interesting features: The lower color stripe can be made invisible (like in TTT): It is 709. If 709 is invisible in the FIRST line, the lower area is also invisible. The upper banding can be made also invisible: It seems that 704 is responsible for colouring in 32 byte width mode. Unfortunately the movement of the scanlines from right to left on the first mode line stays (like in TTT). I haven't found any fix for that. But I found another 'glitch': Interestingly there is a second bug or Atari know the first one and try to workaround it: If you build a DL with modelines of mode '3' (same as mode 2/GR.0 but with 10 scanlines per modeline) you can build a screen of 24 modelines without any distorsion (which normally would mean 240 scanlines in a 'mode 2 compatible look' - but wait: The last but one mode line is a mode 2 line with only 8 scan-lines!!! So someone cheats here! Eventually someone could check this on real hardware too, to verify this antic 'workaround'... Beside this I fixed my images and attached them (last line is now 2x1). So please update you files accordingly. Because I try not to bore you, there is also a new one which doesn't took so much time... @Tebe: I would appreciate it, if you could block G2F-mode 1 & 4 for the last mode line (allow just 0 and 2). This would prevent the situation I ran into... TTJT.zip crises.zip QE2.zip 1 Quote Link to comment Share on other sites More sharing options...

Irgendwer Posted April 2, 2006 Share Posted April 2, 2006 (edited) Updated... F. Thanks. A short information on your news page regarding the update would be nice, since you modified the old image by yourself with a garbled result and the download counter indicated that there were some people which downloaded your modified version allready. BTW: I'm not a friend of publishing modified versions under my name... (Beside the fact that I understand your intention.)

Irgendwer Posted April 2, 2006 Share Posted April 2, 2006 BTW what about colors? The Fandals screenshot of Crises is very different to the one above. Yes, this like Fandal allready mentioned depending on the palette used for emulation (like a adjustment of your tv-set when using the real machine.) The palette which is delivered with G2F represents something like an optimal color representation. AFAIK this cannot be reached with the original hardware. On the other side the palette of Fandal's screenshots represent IMHO a more or less suboptimal color variancy which is easily topped by my real machine. But this a dangerous subject, because different emulation palettes can be regarded as different religions... IMHO the 'true' depiction of the image is 'in the middle' of both screenshots... BTW: @Tebe: Loading of color palettes in G2F would be a nice enhancement. Quote Link to comment Share on other sites More sharing options...
emkay Posted April 3, 2006 Author Share Posted April 3, 2006 BTW: @Tebe: Loading of color palettes in G2F would be a nice enhancement. For God sake... NO The pallette is the most accurate to the XL series. On the XE ony one colour isnt that correct, but that is a problem of the different machines. Actually I don't know, why Fandal uses the fully "off" pallette... free changing of pallettes ends in chaotic results.... Quote Link to comment Share on other sites More sharing options...
