  • It only looks like US currency doesn’t have counterfeit protection features if you only see it in movies or in pictures there are actually a lot of little things that make it difficult to counterfeit. First is its made of a specific cotton linen blend that has a very distinct feel and if you handle cash regularly you can absolutely tell just by touch if it is printed on regular paper and there are markers you can buy that react with it to verify the material is correct. Parts of the bills are also printed in special color shifting holographic inks that would be very difficult to duplicate on a small scale. The hardest one though is there are lots of things that only show up on the bill when you hold it up to the light like a different portrait of the president on the bill in the lower right hand and a strip that is between the layers that has the denomination printed on it. There are also numerous other small things that add up to make counterfeiting quite difficult. They don’t do of of these on $1 bills though since its not worth counterfeiting anyway.

    tldr; there is actually a lot of security features on US currency also I don’t know why I know all of this or why I’m bother to post it to shitpost.












  • A few things I have observed over the years you might want to check. Take a flashlight or something and look at the actual contacts in the port and see if they are bent. Sometimes the old cheap 4 in one carts have poorly made PCBs what arent beveled correctly or are too thick and squish the pins and they no longer make good contact. It looks like an official one in the pic but unless you have had this since new who knows what someone threw in here. see here for some more info on that

    Also these backup carts do just sometimes go bad though I don’t know if I have ever seen an official one go bad but buying a new one to test may help with that as they aren’t that expensive. They also usually have lots of built in features like an action replay and acting as an extended ram cart. Just make sure to try and check that the pcb is made correctly with that link above
