I cannot update an existing 2-Port ROM nor can I create a new one. This issue sounds like it could be related to the .lst (list) problem where some names are "Altera" instead of "Intel FPGA."
However, I haven't been able to find a .lst file that references the ROM IP. Strangely, I am able to create a 1-Port ROM. It's just the 2-Port ROM that does not work.
I'm using Quartus v18.1.0 on 64-bit Windows.
Can you use HDL to instantiate the ROM as a workaround at the moment?
