Are you able to update the display fast enough to make something playable?
Hello Ciaran,
The screen is in fact a background and is drawn in a millisecond
The movement is still unknown to me. I need to learn how do the sprites work in this graphic mode ...
Of course the idea is ... AGD games to V9958, why can't one dream a bit?
cheers

Hi John,
big thanks for sharing these videos, good work!
V0 and V1 works same on my setup.
V2 in mine does the same than V0 but using interrupts, while V0 uses a V9958 function
Maybe something went wrong when I copied V2 to the VDK file ... anyway, it doesn't matter as the point was to confirm
that when we do mix two images, these are not blended together (as it would happen on the MC6847), instead the screen
doubles vertical resolution and interleaves lines from image1 and image2, so if image1 had only the even lines of a big image
say 256x424 and image2 had the odd lines, then this mode 'restores' the image giving much better results.
There are programs that convert PNG images to this format creating the two files that I add together later.
I have used this mode for images and it really makes a big difference.
The only problem to share those programs is that reading a double image of 2x256x212=108,544 bytes requires streaming from the CoCo-SDC
not a big problem because Darren Atkinson gave me the needed clues to do so on the Dragon. I mean you need to have a CoCo-SDC because
by now I don't know if this could be possible with the Dragon-MMC ... maybe Phill could tell us something about that.
cheers

just an update on the Foggy's screen.
I have entered the page for this game on Rucksack Games and have been tweaking the colours on the palette used in the program
and have been changing a bit some tile colour combinations when needed.
In the end I got a result that is almost a copy of the original from AGD for Spectrum
The colours are a bit pale on the reduced photo, but I can assure that, on the screen, they are bright and look very nice!
To me, this is very promising!
cheers

Hi Pere,

It's all looking great. I do have a Coco-SDC - so if there's anything I can test my end to help you, I just need to know how.

Thanks

John

That's really good news! Thanks a lot for your offer, I will tell you when I have things to be tested in deep!
When I have the time to review all of the programs that 'load and show' images in G6-G7-Screen12 modes
I will put them into a VDK file and then I would need to send to you the images that are really a big pack.
The simple page need some 82k and the double vertical definition about 102k, so eight examples in 6 variants
add up to more than 8 Mb, not too much to be zipped ...
cheers

Hello,
after a lot of testing and praying, I have got the objects and the sprites to appear on the Foggy's screens
Now just to practice will try to make them move, well let's say that will instruct the V9958 to paint them
at the new position ... a hard task that the program will not do from now on, just change coordinates, hopefully.
These are the four screen I am using for test purposes.
cheers

this is a video of the first Foggy screen with the three sprites in it already moving
thanks to the hard sprites pffered by the V9958. Th eprogram doesn't erase nor paint any sprite ...
I have found that the .mp4 file was not allowed to attached, so I have zipped it ... despite it is even bigger thna the video :-(
cheers
