Controller support remains central to the Neo Geo feel. Fighting games like King of Fighters and Samurai Shodown demand precise inputs and timing. Bluetooth controllers, USB gamepads via OTG, and even virtual on-screen pads each change the experience. On-screen controls are convenient but rob players of tactile feedback, while physical controllers restore muscle memory and competitive viability. Emulators that include robust mapping and support for popular controllers (Xbox, PlayStation, 8BitDo) offer the clearest path to authentic play.
