 # Atari VCS 7800 linker configuration file for cc65
-# This cfg file adds the a78 header in front of the image
-# If you want just the ROM you can mark the __EXEHDR__ as weak instead of import
-# But for the most common use we add the a78 automatically as it
-# contains info about what kind of cart the build supports
+# In order to add the a78 header to the build you can add
+# "--force-import __EXEHDR__" to the command line
