Hallo allemaal,

> I must have missed something but where?

As usual I stumbled upon two things by accident just ten minutes after 
sending the previous email. It seems that two pairs of zero-page addresses 
are used during the decoding. One of them is loaded with the value $0145 
and is incremented. From the other one the high byte is loaded with $01. 
Where possible I replaced $01 with $08. But no success yet. 

An much easier way is to use the $08xx area for my variables. But that 
leaves me with just about 60 stack bytes. Who knows a way to find out how 
much stack is used? One way: fill the stack with, lets say, $55, do some 
havy things and then check what is left over of the $55's.
Any other idea is welcome.
