On the game selection press
and change the game difficulty to "1" and set rounds to "1:5". This makes it so the CPU has to win 5 rounds so you can keep trying to beat them, as you only need 1 round to win.
Most opponents are easy except for the last boss Gaoh. I'm not an expert on SamSho so I only know how to cheese it. For that I chose Mina who has a variety of ranged attacks that I used:
+
map this to a shortcut as it's your main attack. Fires a heavy arrow directly in front of you. Hits mid and has unlimited range.
+
fires a low arrow directly in front of you, hits low and also has unlimited range. Mix this up with the one above.
+
fires an arrow in an arc but only hits your opponent when you're both on opposite ends of the screen. Good for those situations.
These three moves will beat most enemies provided you mix them up. The only problem is Gaoh who blocks most attacks. You need to catch him mid jump or attacking. It will take some luck and retries. You can use the save system (
) to save/load when you get an attack in on him. Also, if you lose to him, you can just retry. Lastly, you can play as any character up until Gaoh, then lose, and switch to the required character.
