Hi!,
You can't change the screenmode (yet?), haven't done anything on HellChess for a year now. Working on something else.
You can connect an Amiga and PC over the internet, configuration isn't easy. You need to know the IP address and port and configure that in the settings menu. You also need to configure one as a 'server' and one as a client.
The lite version cannot be compared to the bigger one. The menu structure was written seperately for them, hence the difference in usage.
The skins are usable in Version 1.2 of HellChess. If you've got CGFX you should use the 16bit version, it looks much better than.
