>>56749623Yes there are lots of guides to spot a fake cart, you can google it, here is one:
>https://consolemods.org/wiki/Game_Boy:Identifying_Fake_CartsThe best reference is to have a legit cart on hand and compare it to what you're buying. The games with most fakes are the GBA ones. I do a 5-point check:
1. Common sense: Buy from a reputable vendor that allows returns, anybody can post pictures of a genuine cart.
2. 2-digit imprint: The least common things found on fake carts but requires a keen eye or angled image to spot the factory stamped code.
3. Font: The ESRB "E" is often wrong. The font on fakes is either too thin or too thick. Also true for the font on the top and back of the cart itself.
4. Label: It is obvious when you know what a real one looks like but Pokemon games have different reflective effects on the label.
5. PCB: This is probably the most important since it affects functionality and it's not just aesthetics. If you don't have the cart opened to see board hopefully you can get a view from the bottom to see the contacts and some of the font. On transparent GBA carts you can also see the board through the back. You just need a reference to know what it looks like. Also check the condition so there is no water damage or bad contacts.
