###How?

We iterate from \$y=0\$ to \$y=30\$ and from from \$x=0\$ to \$x=39\$ for each value of \$y\$.

We first define \$X=x-19\$ and \$Y=y-15\$.

The variables p = X * Y * b < 0 and q = Y > 0 ^ b & 1 are used to determine what do draw in each quarter according to the block \$b\$.

From now on, both \$X\$ and \$Y\$ are squared in order to easily test absolute positions within each quarter of the field.

The expression x * 24 % 35 > 2 yields false if \$x\$ belongs to \$\{0, 3, 19, 35, 38\}\$ (the positions of the vertical lines) or true otherwise.

The expression ~16 >> Y % 62 % 6 & 2 yields \$0\$ if \$y\$ belongs to \$\{0, 2, 12, 18, 28, 30\}\$ (the positions of the horizontal lines, excluding the net) or \$2\$ otherwise.

The variable \$i\$ is defined as the result of a bitwise OR between the two values above, and is therefore interpreted as:

• 3: space
• 2: |
• 1: -
• 0: + or T

The expression (d ? Y : X - 87) > 169 is used to crop the field according to the game type \$d\$ (single or double). The similar expression (d ? X - 87 : Y) % 169 is used to draw the T's at the appropriate positions.
