I'm currently working on a very simple program that tries to convert an image into a screen 2 suitable version. Here are some samples. Comments and critiques, please...

What is the source of the images and on what platform do you convert? Is it an MSX tool converting from another screen mode to screen 2 or is it a PC tool converting a GIF, JPEG or whatever file to screen 2?

Meits, I'm programming it in Blitz Basic. It's a PC program, since an MSX would be TOO slow for that. Basically it loads an image and tries to create an MSX version of it.

Artrag, I know Jannone's converter. I think it's really impressive, but I don't like dithered images for MSX. IMHO, dithered images only look nice in higher resolutions. My converter tries to mimick new colors by interlacing lines. I thnik it looks better for low resolutions, specially if you're displaying it on an CRT TV.

Anyway, I'm more curious about your opinions on image quality.

I really like them, the color are nice and appears to have more colors on screen. Good job.

Nice to have a converter with a different approach, it complements existing converters rather than competes with them. The pics look good.

Very impressive.
I am thinking to the tons of black and white loading screens of the '80s imported from spectrum.
With a tool like this msx probably would be more appreciated in that years!

Very very nice.
Like you, I never liked dithered images on the MSX.
But your technique of interlaced colors is very well put to use with this converter.

Very good work.

Nice new approach. Though I think you're still doing dithering, just not Floyd-Steinberg style or ordered or other conventional kind of dithering. Are you directing certain colors to odd/even lines?
