A600hd

[mongo]

Some Amiga fan said to me that my problem with the colours using composite must be related to the copper. So, I won't solve the problem if I don't change to RGB. It's a really interesting subject, because it involves programming. Now, I am building another A600 with one more mb of chipram; maybe I could change something if the memory has something to do with the problem.

It has nothing to do with the copper. Any problem with the copper would appear the same on the composite output as it would on the RGB.
