How to initialize content of a RAM without using Megawizard

Well it doesnt complain, but the Altera coding guidlines dont have any mention of textio in there.

I still think the easiest method to make it work will be by outputting a constant into a package (or the entire package). I still dont understand how if you generate a text file from a script or some C code, you cant generate a package aswell/instead.

Otherwise, you will have to raise the issue with altera via mysupport and see what they come up with.
