Quartus Error: Can't place all RAM cells in design - Seeking Help

Hi everyone,

I'm encountering an issue with Quartus where I'm getting the following error:
"Error (170040): Can't place all RAM cells in design
Info (170034): Selected device has 720 memory locations of type M9K. The current design requires 774 memory locations of type M9K to successfully fit.
Info (170033): Memory usage required for the design in the current device: 108% M9K memory block locations required"

I'm using the DE2-150 board and trying to display a 680*480 image. Interestingly, the default example code for DE2-150 works for this resolution, but my custom design is running into this RAM issue.

Also, the default example code uses two ROMs. How can I adapt this to use 680*480 ROMs?

Any help or insights would be greatly appreciated. Thank you!
