Loading data shall be done as follow:

* Right click on the ROM component and click Load Image.
* The image you want to load is a raw file (format described below).

The raw file's format is specific. The first line has to be "v2.0 raw" then the file can be completed with hexadecimal data corresponding to your code. In addition, the number of byte per "chunk" must correspond to the ROM's data bus size. This is one example for 16 bits width data bus memory ROM:
