Takes input as (block)(double), where block is either \$1\$ (top right), \$2\$ (bottom right), \$3\$ (bottom left) or \$4\$ (top left) and double is a Boolean value.

###How?
We iterate from \$y=0\$ to \$y=30\$ and from from \$x=0\$ to \$x=39\$ for each value of \$y\$.
We define \$X=(x-19)^2\$ and \$Y=(y-15)^2\$ in order to test absolution positions within each quarter of the field.
The expression x * 24 % 35 < 3 yields true if \$x\$ belongs to \$\{0, 3, 19, 35, 38\}\$ (the positions of the vertical lines) or false otherwise.
The expression 16 >> Y % 62 % 6 & 2 yields \$2\$ if \$y\$ belongs to \$\{0, 2, 12, 18, 28, 30\}\$ (the positions of the horizontal lines, excluding the net) or \$0\$ otherwise.
The variable \$i\$ is defined as the result of a bitwise OR between the two above values, and is therefore interpreted as:
- 0: space
- 1:
| - 2:
- - 3:
+
The expressions q = y > 15 ^ b / 2 & 1 and x > 19 ^ y > 15 ^ b % 2 && X are used to determine what do draw in each quarter according to the block \$b\$.
The expression d ? Y > 169 : X > 256 is used to crop the field according to the game type \$d\$ (single or double). The similar expression d ? X - 256 : Y - 169 is used to draw the T's at the appropriate positions.
