Hat aber das Modul eine Funktion um in's Basic zu kommen? Man kann ja schlecht ein Programm laden, wenn das Modul noch läuft.
Disable the cartridge autostart of the game. The original Commodore kernel was unfortunately designed to provide protection of commercial cartridges against reverse engineering and will not allow to load and run a program while a game cartridge is inserted in the module slot. Disabling the cartridge autostart can be achieved either by installing a Kernal-ROM that allows to bypass the CBM80 check (for example "SpeedDOS") or by using a cartridge expander or switch that allows to disconnect the EXROM line.
