Hi good afternoon.


How can you please create a ROM as in the title and then start with the "|world"?
I've read something about it, but I do not understand it.


I would like to get to know the basic principles until it becomes executable and what
you have to pay attention.


I am not looking for anything complicated, but a gentle construction.


Thank you.
Greeting

Hi Funkheld,
       your name would suggest that you are German? If so, I'd recommend you download this book and check out pages 25, 105 and 106.
