How to tell if circuit board inside carts are authentic and belong to specific carts

[Jayleonis | 16]

Im seeing carts on ebay for sale with photos of the interior circuit board.  Is there a resource I can check to see if its the right one? or how are you supposed to know if that board belongs with that cart?

 

edit

I found this resource

although im still unsure.  the board in the photo looks correct in terms of layout of the circuitry but the manufactuer says toshiba which the one on snescentral does not.

With NES, SNES and N64, the code on one of the chips will match the code on the label.   Not sure about Genesis or Master System.

SNES Central is the best for SNES games (and Bootgod for NES) but this info is still very obscure and incomplete in general.

Here are 6 Secret of Mana PCB variants, only 4 of which are on SNES Central. Matching the chip code and just seeing that the board looks like all the other PCBs for that console is all I do unless I’m checking something really expensive.

If you're paying with PayPal I wouldn't worry about it. I just buy whatever and if it turns out to be the wrong game I get my money back almost instantly.

Unfortunately, some games had numerous manufacturers for the chips. Your best bet is to make sure the PCB is legit with the Nintendo logo (or appropriate third-party publisher logo in certain circumstances) and check the actual codes.
