I'm not sure I understand? VERA will always have Color Zero as transparent.And one more thought to the background color. When porting from C64 you start out with the 16 colors the C64 had. CX16 treats color 0 as transparent. So setting the background makes for a color in that case. I can work around the for now, as one color in my C64 palette was unused and I changed it to be background and modified the import, but it would be nice to be able to change the background color.
Forresten, på hvilken side af vandet befinder du dig? : )
