The resolution of the VES in the MESS emulator is set at 102x58 pixels. Televisions usually have a different visible area which can also be centered differently. A centered resolution of 95x58 should be considered a safe area for real systems. Newer flatscreen televisions might have a larger visible area, if using graphics along the edges it's not a bad idea to add as much as 4 pixels extra in each direction.

While the current version of MESS only displays 102x58 pixels, the VRAM actually extends to 128x64 pixels but the extra (non visible) memory is lost because there's no known way to read it back.

Even though PAL televisions system has more lines vertically, the Channel F displays about the same as on the original NTSC video system.
