Performance is another major benefit of using MAME on a PC. While many of these games originally ran on hardware with less processing power than a modern calculator, the MAME emulator allows you to apply "shaders." These filters can recreate the warm glow of an old CRT monitor, add scanlines for authenticity, or even upscale the graphics to look crisp on 4K monitors. Furthermore, modern PCs allow for "save states," letting you pause and save your progress in games that were originally designed to be impossibly difficult just to collect more quarters.
