c64img is a PHP script that converts an image to an image that can be shown on a Commodore64 (FLI style). It searches for the best possible colors in the 160x200 (X-doubled) resolution, and uses a simple dithering method to distribute errors.
d64-web is web-enabled utility for displaying Commodore64 (D64/D71/D81) disk image contents (directory, BAM and more). It also provides a basic API for working with D64 disk images in PHP.
Up to this moment only works fully on D64 images.
