Nope! I definitely ain't.
When it comes to gaming, I wish I did. But well, that doesn't matter.
The cart itself seems to be too light to have an actual EEPROM chip inside it, and it's so fragile that I think I'll break it if I open it.
Seller says the carts are virgin. My best guess is that they are rewritable, but I have no idea how.
Even in the best of cases, if the cartridges the machine comes with are, and have a battery that allows the games to save, the seller still won't sell just one cart to me
It still is more info than what I had! Thank you!
