 It works by taking a map group and number and array of (x,y) positions and copies them into the current map from the given layout. An example of the `pos` argument:
 - If I want to copy the first 2 columns of a map from y positions 0 through 7:
 ```c
-static const u8 sTestPositions[][2] = {
+static const struct UCoords8 sTestPositions[] = {
     {0, 0}, {0, 1}, {0, 2}, {0, 3}, {0, 4}, {0, 5}, {0, 6}, {0, 7},
     {1, 0}, {1, 1}, {1, 2}, {1, 3}, {1, 4}, {1, 5}, {1, 6}, {1, 7},
     {0xFF, 0xFF}, // to signify the end of the array
