|  Graphic data file issue
Hi George,
I don't understand what you are trying to do with loading and saving again the data. If I understand it right, when you load the data first, it is correctly loaded at $0800. Why do you try to save it again? Although, if you are blindly following my previous example and make the data compile to address $1800 then you should replace the two assembly lines with ORG $0800-2 and DW $0800. After that you'll need no other steps like transferring to $0800 and saving again because it will load to the correct address.
You have to understand that the BASIC character screen resides at $0C00-$0FE7 and the colour map at $0800-$0BE7. If you load or copy into these areas something then change the content of the screen with any kind of interaction you cannot be sure that your content will not change therefore it is advised not to do anything like this.
