Hi! I am working on a version of MadLib for AuxMemApple. It is a ProDOS system program. I load some code to the unused space between $0800 and $1000. Excuting this code seems to crash the system: I get the monitor at location $A504. I can just store this code in the main module, but I like using extra unused system memory via my Cubbyhole optimization technique. :) When I check the size of the data loaded to this memory, I get the number 65088. I'm using ProDOSi to load the data. I attached the config file and the code that loads the data.
