Oh wow!! Very impressive!! It's not an MSX, but it uses the same VDP. I do not see any color clash though, how do they manage it?!

The youtube description says it uses horizontal resolution of 64px, so I guess it uses blocks of 4x1 to avoid color clash.

Oh I see! I watched the video in the integrated player here in the forum, so, I did not see the description, just read it now. 4x1 blocks seem like a very good idea. I used 2x2 blocks in Tales of Popolon just to make them blend with the 2x-size resolution sprites. But 4x1 seems like it can get quite interesting results!

You can update the sole color table

Good point about only having to update the color table, I had not thought of that! There might be implications of having a pixel-by-pixel vertical resolution, but it will probably result in a net speed up compared to 2x2 blocks. Very cool idea!

You do not have to worry about color clash too
