I don't understand the question.

SDD1.vhd has the ROM_DO port, and SDD1 is called as an entity, where ROM_DO is mapped to ROM_Q port in SDD1Map.vhd. If you take a look at ROM_Q in a "find all in folder" in your IDE/text editor, you will see that ROM_Q comes from the main module (main.v). That module is called in SNES.sv (the top-level emu module), and connected to .dout on the sdram module. So ROM_DO from SDD1.vhd just goes to the SDRAM, because the ROMs are loaded into SDRAM.
