Here are screenshots from the demo. Not too bad for being MSX1, right?

dvik, can you place some converted pix with large plain areas (such as that last sunset pic) but then pre-dithered? Preferably random and

Using pre-dithered images will probably improve images like the sunset even more. Shouldn't be too hard to test. Just need to create the 105 color palette in photoshop or similar.I guess the dithering needs to be done on only parts of the image though but thats what the image editors are for Wink

just dither the whole pic, don't bother about only applying it to large areas..

How were these non-flickering screenshots made?

Is this a blueMSX feature? (Mix 2 consecutiive frames?? Or what's the idea?)

blueMSX has a display option where two consecutive frames are interpolated based on the clock of the MSX and the current scanline of the PC monitor. So the output is in most cases as smooth in blueMSX as on a real MSX. This is a bit CPU intensive but the result is good on fast PCs with LCD displays.

A side effect of this interpolation is that sometimes two frames are mixed 50/50 and if you pause the emulation at that point you can take these screenshots.

So the interpolation is really a resampling the video stream from the MSX refresh rate, e.g. 50 Hz, to the PC monitor refresh rate. So its kindof the same as resampling an audio file from one frequency to another. The algorithm is adaptive though, so it compensates for for example lags. I guess the result would be quite good with fixed resampling constants too but the adaptive one seems to work a bit better.
