ok. so i was looking for ds games online for my son for Christmas and come across this website (*removed*) Am i to understand this will play on his 3DS? It says to check the Ver. of your DS before ordering for compatability?Where on his 3DS do i find this? Does it just slip into the regular card slot? Do you have to alter the 3DS in anyway or will it damage it? I'd hate to throw away money i don't have for something that won't work.Please help?!? In plain English please!! LOL, I hate sounding stupid about all this, but pretty clueless in the gaming tech, whatever. THANKS!!
