Programmable Character Generator

There was a port of Pac-Man for the Sharp MZ-700. Its graphics were very blocky due to the Sharp MZ-700 not having a graphics processor. However, if an external Programmable Character Generator chip was installed to the PC, the graphics will appear more accurate to the original arcade game. It's a similar case with the MSX port of Mappy. The characters and objects in the game were comprised of letters, numbers and basic shapes due to the MZ-700's lack of a graphics processor. The graphics would end up looking similar to the MSX version of Mappy if an external Programmable Character Generator chip was installed to the PC. In other words, the PCG board works wonders when it comes to making Sharp MZ-700 games appear similar to arcade or MSX games.
