I would not get these carts anyway, as they are not made with the same manufacturing process as an actual SNES cart. Remember that warning about the SF2 Anniversary carts? Same thing applies here. Don't risk your 25 year old system on a cheap repro.
As someone who has made repros I can tell you a repro is just a regular cart that is opened up, reprogrammed and had its label replaced to reflect the new game on the board. Very rarely does anyone make a new outer shell or board inside. Though it does happen.
If you actually read that warning it stated that because the system is deemed retro, the carts can’t be warrantied to replace your system if they fry it. Aka no difference than playing any cartridge.
I don’t know where you get your information from but I bet it’s a stinky place.
