If you compile a win32-program you will have a total virtual memory, 
that means that your pointer values don't have anything to do with the 
physical ram. A pointer associated to $a0000 actually points to nowhere.

If you really want mode $13 you need to compile for dos, cause then 
windows sets up an old-style 8086 environment. Unfortunately the 
download page says:

"Sorry, no Dos release yet. The Dos platform is missing a maintainer and 
is not of acceptable quality for 2.0."
