Transform the look of ANY CGA game on the Olivetti Prodest PC1.

This video shows my custom **CGA Palette Loader** — a tiny DOS utility that lets you load your own RGB palettes directly into the Yamaha V6355D video chip. The PC1 includes a fully programmable 16‑entry RGB DAC, which means you can override the default CGA colors and create completely new looks for classic DOS games.

Perfect for experimenting with:
• custom color themes
• NTSC artifact color tweaks
• composite color modes
• Sierra AGI / SCI0 games
• 8086‑era DOS titles

If you're into retro hardware, CGA quirks, or the Olivetti PC1, this tool opens up a whole new world of visual customization.
