Use a loupe or take a photo of the top of the chip under good lighting?
The question really is, did the original installer wire it correctly?
I can tell you what some of the points on the board are.
From left to right; +5 volts, GATE_WFCK, the 3rd should be DATA, but I think they got it slightly off, last is a GROUND point.
So, you need to know which pin on your chip takes the GATE_WFCK, and move the DATA over if is wrong.
PIN 6 is to GROUND? That seems wrong on any chip.
It could be a mis-wired 4-wire chip. I think you need to put the wire that is on pin 6, and put it on 8. Then put the DATA to pin 6. Move the wire on the board from where it is to #6 in the pic below. Also attach that free wire to PIN 5.
If it was an old PIC in a 4-wire REI configuration, say a PIC12C508, you would see this:
PIN - function
1. - Vdd (+5Volts DC)
5. GATE/WFCK
6. Data output to send the correct copy protection serial message so the console accepts the disc.
8. Ground
