Archer30, pcx16 is game internal format, having nothing common with external pcx with 16 bits. MMArchive automatically converts bmp to internal pcx8 or pcx16 format during import. I don't know, whether GrayFace counts number of unique colors in image (256 or more?) or maybe he relies on bmp format (8 bit, 16 bit). I think, the first one. Thus the only thing you need is to import picture with more than 256 unique colors in its pixels. You will see in tests, if everything is alright.
