+  Game specific notes...
+
+  * Sonik Fighter
+
+  The game is encrypted, and runs with an obfuscated daughterboard in place of the CPU.
+  Even when I have the attract working, accepting coins, getting sounds and accurate inputs,
+  the game is still not working. Once coined, there's no way to start a game.

+
+  Colors are wrong due to can't find a way to set the palette.
