Title: Need help: Who can check this on a real CPC with CTM connected?
Post by: Devilmarkus on 15:58, 25 June 12
Hi peeps,
I made a new overscan picture in MODE 1, no rasters or other technical things.
For this I want to know, how it appears on a real CPC with the CTM connected?
So, who could transfer it and try?

And, of course, take a screenshot, too....

Working on it. Provided it loads OK from tape, I'll have a picture for you shortly..

EDIT:: btw, if you want more doing DM, just provide a CDT made in javacpc or whatever (with the high speed flag set)

Yeah the CRT looks very crispy here.
Maybe it looks so, because taken photos always appear much more bright than the CRT shows?
What is your opinion, Devlin, do you like this kind of dithering, or is it too pixelish? (Don't forget, that only 4 colours are used)

Perhaps you could take more photos with less brightness?

@phi2x:
JavaCPC uses a combination of filters in the upper screenshot:
- 3D Display (uses Open GL)
- Blur filter
- PAL emulation (Adapted from Winape)
- RGB2x filter (adapted from DOSBox)
- Monitor mask (rounds the edges a bit)

Only the RGB2x filter looks like this:

It looked better than it did on the emulator - if you want to see it with brightness down you might as well just reduce the brightness of the photos, that's what it'll look like..


in comparison to the emulated screen, I think that that kind of image is a bit dark to work well with dithering..

Devlin, lovely photos. I especially like the moire pattern that only appears when the second photo is shrank!

I like this technique, and the effect on javacpc is very close to a real cpc, but for me that picture had too much noise.
I would like to see a more cleaner picture, perhaps hand pixellated in this way to see what kind of results can be had.
I know it is easier to convert images using tools. I think this method has potential.
I don't think it can be appreciated as much as a cleaner image.

The problem is:
If you reduce the dithering (black areas go black) the image looks much more bad!

Ok, this PAL emulation on c64 can do a lot of things. Quite nice to play. But honestly - I only need a single option : "Make it like the real machine". Quality before quantity ;-)
JavaCPC offers already more than needed. I mean ... anything else is just a virtual machine, not a CPC anylonger.
People shoule invest more time in correct emulation of the keyboard (scanning) on emulators ;-) Feel free to throw tomatos now  ;D

You can do almost the same in JavaCPC...
Wait, will take a video... :P

Few results: (Some are fast enough to get 50fps...)

Well, the c64 video is really great, but it doesn't try to emulate a typical c64 setup (either a tv or a Commodore monitor). Instead there are lots of options (like persistence) that apply to very old monitors and some (like the low-refresh strobo-rolling that you can't actually see, you only see it when such a monitor appears in a movie or on tv) are just made up.


It does look superb, but it could have been much simpler.

Nice screens effects! :)

About your first post; With only 4 colours you can render every pictures using dithering, and looking far.
It's the same concept as 4mx3m street advertising.

Perhaps its possible ;)

Adding a new "smoother" CRT ditherer to JavaCPC
