[ORTA]

I'd like to know what is a saturn cart swap trick,

and what is the effect of it on sega saturn consoles :blink:

It's bad in every possible way.  You should never do it.

What exactly is it? I've read it here in this site, someone posted something like that, if you can't tell me how it is done, then please tell me why other people do it and what is the effect of it on the console I'd just like to know
