     TODO:
-    - Don't know where the ES8712 samples come from;
+    - What does the ES8712 control? There's definitely no ADPCM chip or sample ROM here;
     - Main CPU banking is wrong;
     - Some inputs not understood;
     - A bunch of missing port outputs (including payout);
-    - NVRAM;
     - screen disable? Start-up fading looks horrible;
     - Game looks IGS-esque, is there any correlation?
