Jack Burton inspired me to put together this production, released at Edison 2015, featuring some of the very nice Scifi and Fantasy art by Frank Frazetta. It demonstrates a converter and source to enable higher quality pictures on Amiga OCS.
I already had an ILBM converter and looked to extend it to convert PCHG, so I had a look at the format from the pictures he sent me. It cannot rival the excellent Amiga AGA graphics quality, but extends the color capability of OCS by ...a fair amount :), and in a way that doesn't hog CPU or DMA resources.
Enjoy the production and if you're a graphics artist or coder, explore the possibilities with this format! A CLI command to test your conversions, and an example source to convert one of the pictures shown is included.
