Gaming Text on back of cartridge.

[MichaelB]

What does it mean, it differs even on the same game cartridges and the text below it is also different.

The serials should be the same between two copies of the same game unless one is fake or a reprint/different region

No, look same game no fake.

N as you may know is software version
J is unknown but I would speculate is a factory number (I also have many 22s and 34s in my collection)
The triangle of course is pin 1
The last part of the PCB text (in this case IRC02-01) looks like a model number (they seem to increase with some vague correlation to release date)

Thanks! I was wondering what it was. The other cartridge is V-6 and mine is U-6 Is there any difference between these?
