The cc65 memory map for the ATARI XL has two holes so the linker needs hints which object files go where. Source changes lead to object file size changes requiring now and then to rearrange the object files.
The new Atari XL target allows cc65 programs to make use of
the shadow RAM. This allows to turn aon all features of the
web browser - and will allow for additional improvements to
come :-)
Don't be afraid, I'm not trying to have more retro platforms than "real" platforms ;-)
The platform 'atarixl' will replace the platform 'atari'. However I need both for some
transition period.
