d. IMPORTANT; copy the files extracted from the ROM inside the Emulator's folder
e. In the emulator folder, Open the EMULATOR.INI file and copy-paste the path to locate the ROM files. It is in line 9, and you should substitute that for:
----
Dir1=C:\path of to the ROM files here (or the desired path)
----
f. Load the ROM by executing the Emulator first and then go to the emulator-load ROMroom
g. To solve the calibration problem with the gun (when you extend the window), Press F2+F1 to select the right option, then calibrate the gun for player 1. You will note that the movement of the mouse does not tally with the one from the aim, but at least the aim tallies with the pointer when you shoot.
