I am sure they are directly read from rom;
For example, take the snes for example that has 64kb ram; if you want to display a full screen 320*200 image on the snes (just an example, snes dosn't have the 320*200) in 8bits colour mode, this is 64kb of memory, if you put this image on ram before sending it to vram, all the ram would be filled! where is then the game code?, the variables etc..., the system would just crash.
Coin up Arcade games are like that also, very small ram.
