Commentary: Neo Geo CD Emulators on Android

BIOS Files

: You must provide your own BIOS. For RetroArch, you typically need neocdz.zip or uni-bioscd.rom .

Yet the ecosystem is messy in practice. Multiple emulator projects exist with different priorities: accuracy versus performance, features versus legality. Some prioritize cycle-perfect timing and exact sound emulation but demand beefier hardware; others aim for wider device compatibility, sacrificing minute audio or timing details. Users must balance those trade-offs against their device’s CPU, battery life, and preferred input method. The community fills gaps with user-made BIOSes, patched ROMs, and translations — resources that blur legal boundaries even as they preserve gaming history.

  1. Kizuna Encounter: Super Tag Battle: A 2D fighting game featuring a vast array of characters from various SNK franchises.
  2. Samurai Shodown II: Revenge of Zen: A critically acclaimed 2D fighting game with a rich history and complex gameplay mechanics.
  3. The King of Fighters '94: A pioneering fighting game that laid the groundwork for the popular series.
  4. Art of Fighting: A 2D fighting game with a unique gameplay mechanic and an engaging storyline.

Purists will argue that touchscreen buttons are heresy for a fighting game. They have a point—executing a Raging Storm on glass is an exercise in frustration. But Android’s strength is its peripheral support. Pair a Backbone, Razer Kishi, or even a PS4 controller via Bluetooth, and your phone becomes a more ergonomic Neo Geo CD than the original. The console’s original CD controller was notoriously mushy; modern Bluetooth pads offer superior precision.
