1. Video Aspect Ratio: Neo Geo games run on a 4:3 CRT standard. Set your Video > Aspect Ratio to 4:3 or Core Provided. Never use "Stretch to Fill," as it distorts the pixel art.
2. Scanlines: Neo Geo games were designed for CRT monitors. In Settings > Video > Output, turn on "CRT SwitchRes" (if your display supports it) or use a shader. Go to Quick Menu > Shaders and load a preset like crt-geom or zfast-crt for an authentic arcade look.
3. Overclocking: In the Quick Menu > Options, look for "CPU Overclock." Increasing this slightly can reduce slowdown in heavy fighting games (like Metal Slug 2 or Samurai Shodown III), which were notorious for slowdown even on real hardware.
