|  Re: Converting gfx made on PC
A minor correction to the above post: clearing "Optimize for PAL color filtering" is actually not needed when dithering is disabled, since it has no effect without dithering. Also, if a GIF file with the Plus/4 palette is successfully detected, interpolation is automatically disabled.
If you create a Plus/4 palette by saving a screenshot in VICE, then - at least with the version I tested - using the BMP format is recommended, as PNG files are saved in 24-bit RGB format, and PCX have 256 colors with random garbage in the upper half of the palette (this prevents the Plus/4 palette detection in p4fliconv from working).
For "pixel exact" conversion with p4fliconv, you need a GIF or XPM format input file, because the library I used for reading images automatically converts BMP and PNG files to RGB format.
