Virtua Cop 1 required a CRT. I prefer LCD, so it was annoying to have to install a CRT to play Virtua Cop 1.
So I created a PATCHED ROM that can be played without a CRT.
In the video, it is played with an analog stick, but 'GUN IO TYPE2' also uses the same 5V signal as the analog stick, so GUN IO TYPE2 can also be used.
Then, you can play Virtua Cop on the large LCD just like HOUSE OF THE DEAD4.

Both the Virtua Cop dedicated IO board and the general ‘Model 1’ IO board can be used.
Connect 1P X-axis and Y-axis to analog CH1 and CH2 and use CHUTE #1 switch as OFF-SCREEN switch.
Go to ‘GUN SETTING’ - ‘MANUAL ADJUSTMENT’ in the test menu and set
ADXMIN=1
ADYMIN=1
ADXMAX=FF
ADYMAX=FF

Set to ‘Free Play’ to disable the coin sound.

edit -
If you use a regular IO board and the cursor movement is strange, you need to set it as follows.
ADXMIN=1
ADYMIN=200
ADXMAX=FF
ADYMAX=2FF
Conversion is possible from Daytona USA to Virtua Cop without an additional PCB.
