That looks promising — thanks! It's no problem being Mac only as it fills the hole I had with palette-based pixel editing. Though curiously my sample palette.png file that I thought had all 128 SAM colours is only showing 126 in the list in Pixen. I'll have to check it back in PSP to see if it's my mistake. > To get those images onto the Sam, I (like everybody else, apparently) wrote a > script which reads image files and outputs in various formats.

I used PIL for shamview, but that wasn't part of the standard Python installation on either Snow Leopard (at the time) or Windows, but it was under Ubuntu. I found an unofficial build for Windows, and managed to copy a MacPorts-built extension to the standard Mac version, but it wasn't a dependency I really wanted for my build tools. After all that I fell back on processing the PNG file directly, and I'd already got Perl code to do enough for what I needed. Ah well. Si
