If this software is cool or useful to you, consider buying me a coffee on Ko-Fi! There is *no* need to pay to download and enjoy this software! But a couple of dollars would be really appreciated! :)

NOTE: Please download the latest code from GitHub: https://github.com/tursilion/convert9918. I haven't updated my local pages just yet. :)

This program can convert most modern graphics into a form compatible with the TMS9918A bitmap mode. It supports a drag-and-drop interface and handles resizing and scaling, several forms of user-configurable dithering, adjustable color selection, and more.

It also supports multi-color (64x48) mode, a dual-multicolor mode with flicker, and a half-multicolor mode that flickers multicolor with bitmap to get more colors.

Finally, it also supports two palette modes for the F18A VDP replacement - a 16-color palette mode, and a per-scanline palette mode (this mode uses most of the VDP RAM and requires the GPU to update the palette every scanline, but because it runs on the GPU the host CPU is not impacted at all!)
