Is my game real or a fake?
so I'm pretty new to this stuff but I always hear folks mention wanting to see the circuit board before purchasing rarer games. I was wondering how one is able to verify a games authenticity by looking at its board? Is there some sort of known serial number printed on it?
Comments
Look carefully at this picture, using SNES as an example. NES and Genesis boards look similar.
Where it says ROM is the part of the board you want to look at. In that picture, right now that ROM chip is a mask ROM. That is what every retail NES / SNES / Genesis cartridge should contain.
If you see this (EPROM):
Or this (one time programmable EPROM):
Or this (TSOP flash on adapter):
IT IS A FAKE.
If you're at all confused, IN PRODUCT CODES WE TRUST.
Since pictures are better than text. Here's a couple picture guides for you:
Every Nintendo game is given a product code. Here's the one for Super Mario World:
SNS-MW-USA
That product code is printed on the box, manual, cartridge label and mask ROM for Mario World. If the Mask ROM has no Nintendo product code, it will probably be a OTP EPROM instead, thus fake.
NintendoAge has nearly every product code for NES and SNES listed, just search. Here is Mario World's entry:

Lastly, sometimes a non-valuable game will have a replacement for the mask ROM, or there will be two ROM chips and only one is a mask ROM. These are probably repairs, not fakes. Not everything of this sort is malicious with the intent of scamming.
MOD EDIT: If you're not sure about NES games, you can always compare them to the board scans available on http://bootgod.dyndns.org:7777
If some of the numbers on the chips don't match, that doesn't necessarily mean your game is fake. It usually only means that the game was produced at another date.

Anybody have more great resources to contribute? Might as well,get as much in here as we can.

I could gather some more pictures for extra clarification.

Am I mistaken, Guntz, or is your 2nd chip an EEPROM, which wouldn't be a OTP, that would be the EPROM?
The site said it was a OTP EPROM. I don't think the average EEPROM would work in place of a ROM chip.

There are some Amtel EEPROM's that I've used for Earthbound Zero and some others. OTP's generally have the window while solid ones are EEPROM's, though I suppose there could be the oddities, or I'm just thinking of something else and I'm completely wrong, which is very possible lol
As long as you know what the real Panesian carts look like, I don't think you'll see too many truly authentic-looking fakes.
Though I could be wrong too.

The Panesian games are one of the only exceptions to the guide I posted, but really most unlicensed games shouldn't be counted like officially licensed games. I'm pretty sure they use EPROMs. As for the boards, I don't know. The shells are apparently unique to Panesian, but are similar looking to Color Dreams / Sachen.

Panesians definitely use EPROMs. I've seen pics of their boards and did a research to find that they do use EPROMs.
This also means that all Panesians will stop working at some point.

Thank god.

We'll most likely be all gone before they stop working. Besides, if they use EPROMS, it would take a minute to fix it

I just got a copy of Donkey Kong Jr. Math, and I just read this thread so I used that game to test out the process here. I have no reason to believe that someone faked that game, and I believe that the board is legit. However, it doesn't match the Hardware Profile here: http://nintendoage.com/index.cfm?FuseAction=Element.View&egID=672&lgID=297&sID=297
I think I just have an older board. Am I right? Can there be different boards for a game and ones that aren't listed in the NA database? If so, is there a way to get the database updated to include them?
Here is a pic of my board:
Thanks!

That makes sense. There are probably tons of hardware profiles for some games. I didn't see mine on his site either, though he has a few more than the NA database. Your comment here is very valuable for future enquirers. Just because your specific chip numbers don't show up in a hardware database, that doesn't mean your board is fake.

EEPROMs work fine for NES repros. OTP EPROM = one-time programmable, which means you get one shot to get it right. They aren't erasable like windowed EPROMs. Otherwise they function the same.
Also if anyone else has questions, this is the place to ask. Would rather keep all this fenced in to one place on the boards.
