+Needs to be tested:
+
+Normal moves
+	Movement status code handler
+	Scaling, slope, moveDiagonal when slope not automatic
+
+Promotion
+	Test one to each type of promotion for both colors
+	Tests 3 - 
+
+Captures
+
+Moving to/from graveyard
+	how to simulate this? need to know where pieces are in graveyard
+
+Castling
+	similar to move to/from graveyard where one piece is put into temp position
+
+Endstop collision
+	aligning/homing
+
+Set up Debug game test to run through and verify ai, mc, and cv code
+

+		invalid OpCode
+	makeMove
+		if you input message the positions for xi, xf, yi, or yf into moveDirect, moveAlong Edges, or alignPiece they must be valid
