Can we get the screen resolution for the map screen increased to 512x512?

The size of the map screen was because of the ps2, we don't have the ps2 anymore. There is no reason we should have to scroll around the map when it's fully zoomed out anymore.

I'm not asking to make new or bigger maps, I'm just asking for the screen size of the map screen to match the map image sizes. The map screen is 256x256, which means we have to scroll around a 512x512 map image.
