On the Subject of Mega Man Boss Rush

This one is actually Easy Man!

Calculate the following:
(batteries + ports) * (last digit of S#) + 1. If needed, keep the result in range 1-8 by subtracting 8. Press the character in that position, in reading order on the module (ignoring Mega Man in the center).

In the table below, find the sequence of robot-masters, in which the first robot-master matches the robot-master that was pressed first on the module. Press the remaining robot-masters in the order of the sequence.

12345678
Seq. 1
Seq. 2
Seq. 3
Seq. 4
Seq. 5
Seq. 6
Seq. 7
Seq. 8

Sometimes, one of the eight robot-masters will be replaced with an E-Tank. In this case, substitute the missing robot-master with the E-Tank in your sequence of presses. If your first press was the E-Tank, you will need to find and follow the sequence where the first robot-master is the robot-master that is missing.

After pressing all of the eight characters, Mega Man will be replaced with either Mr. X or Dr. Wily on the module (depending on the number of lit/unlit indicators). To solve the module, press the character who replaced Mega Man according to the table below.
