Real-time adjustments

When you sit and edit with RetroPaint you have several adjustment layer settings. This is me turning up the brightness on the cover image from Cauldron II. This is a single layer, YUV color matching and line dithering turned on. You can pick any image in between and start pushing pixels on that. @60 fps on my PC @ 320x200 C64 MC.

Some more images

These images are only here to show that you can simulate/emulate different platforms. Some of these examples are NOT able to run on the actual platforms. The dithering method used here is Floyd-Steinberg with default parameters. Just to demonstrate that you can go from one platform to another in two clicks (if you're lucky, that is).
