Here's the Blinky and Warhawk pictures tacked onto the games.

 

[Edit] Note: I've used <ANY KEY> for getting past the titles, otherwise they would both go right into the game when using <START> or the joystick <BUTTON> (unless only pushed and released very quickly).

These are fantastic! It's time to swap out title screens for Commando on the A8! I assume these are C64 sources? How many colors, on average, did Rastaconverter add to the original 16?

Yes, C64 sources

I don't know for the number of colors, I deleted all "output.png", sorry...

 

@MrFish,

 

Thanks

Autumn Stream. 46 colors. As with Crystal Sunset, the pinks seen in this image are yellow/orange on a real PAL Atari, and look much better.

Here is another image that I've attempted conversions for many moons, and could never get it to my satisfaction. This is the best of the failures.

 

Fellowship of the Crescent Moons. 66 colors.

Digital Visine. 51 colors.

I'm quite annoyed the conversion has stalled at this point

 

 

I was so close!

You're not done till you've wrapped the evaluation counter around a couple of times ?

Sometimes it helps going back to an earlier save and continuing. You might luck out on a better solution as it's fairly random, although some solutions are much more probable to be found.

[Sheddy]

Slightly off topic, but has anyone got rasterconverter pics displaying on Ataris with CPU upgrade, or is it totally reliant on the accelerator having a "normal" speed setting?

[Rybags]

It relies on cycle exactness since register changes can occur mid scanline.

[Sheddy]

Thanks, thought as much. I'm doing a title screen, so looks like some CPU upgrade users will have to miss out

Umm, I wonder what is the title screen for :-) Afterburner? Outrun?

[Sheddy]

Lol. Just some little enhancements to space harrier which are taking much longer than I hoped ?

[Gunstar]

If Rastaconverter is so cycle exact, then why isn't an NTSC version needed?

[Rybags]

Both systems are 114 cycles per scanline.

Normal display is 240 scanlines maximum for playfield, so the extra vertical space isn't relevant for static pic situations like this.

Last Caw. 43 colors.

 

Serengeti Evening. 20 colors.

It's still going, now at just over 1 billion evaluations and about 16 hours later. I'm still not getting the detail I'm looking for. One error looks like a tractor beam placed on the sting ray. The other one is the large gray fish (a grouper?) hasn't an eye. These are the things that most ruin the picture.

 

The image looks like this in Altirra (custom colors used, custom palette for rastaconverter)

 

NormDist had dropped by 0.5 to 40.9, not much improvement for 16 more hours of computation

[Sheddy]

Yeah, that's a shame. If you started over and could adjust till the lighter blue dots disappear to the left of stingray on the destination, it'd probably help. The eye is too subtle to have much luck with most likely

A little update on the two versions of the Green Acres picture I'm working on...

 

Both have improved nicely and continue to improve steadily. I did restart everything evaluating with the latest version of Rastaconverter, which I wasn't using on the first ones I posted.

 

Note that the number of evaluations is incorrect on both of these. Somewhere around 5 billion both of these reverted to counts lower than 2 billion after quiting and resuming (previous quits and restarts were no problem). However, the progress of the conversion was still correct and continued on. So the correct count is the displayed count + more than 5 billion. Has anyone else experienced this?

 

The lower-colored version's evaluation count is quite a bit lower because it's been running on my main machine, on a single thread, and I've stopped it for some long periods of time before continuing.

 

You may notice that I only set the solution number to 10 for both of these. After I finish letting them evaluate I'll redo both with a much higher solution number.

 

Here's the lower-colored version (dithered in Photoshop), which was evaluating to 38 colors and now is evaluating to 68. Big jump.

 

 

 

Here's the higher-colored version (dithered in Rasta), which was evaluating to 70 colors and now is evaluating to 76.

 

 

[Rybags]

Sky much better on first, but the second has much better looking grass with better contrast and brightness.

[Sheddy]

Yeah, the counter wrap is normal on the version 7 rastaconverters. That probably started happening when the multi-threading was added. The speed up was so great that I doubt anyone left it running that long to hit the issue before then.

If that's what's happening it sure is doing it in a strange way. When I saved and quit each one at different times, they were each at 5 billion +. When restarted, one picked up at 1.x billion and the other at something like 600 million. And right now one of them has already ran passed 6.x billion. I'm going to try and let that 6.x billion one run and see if it wraps if I don't quit, because it seems to me to have something to do with quiting and restarting after a certain point.

[ivop]

Probably when it is still running, it's a 64-bit variable. Somewhere during saving or loading it gets assigned to a 32-bit variable and causes and integer overflow.
