Some samples would be great actually, thanks!
I can't seem to find a way to post files here (suspect you can't), so here is a link to download a small collection.
Inside, you will find a few C/G pic files (that on a C64 or in DirMaster, are correctly viewable). In addition, I made BMP images of each, so you can see what they should look like when viewed properly. I also included one C/G animated movie, just in case you find that interesting or useful (prob not as much for Playscii, but whatever).
Hope this helps!
