I played some of green version on an emulator a long time ago.
I say if you want to get it, you should definitely ask.
I was just checkin it out on ebay, and used ones run around 20 bucks.
some are even 14.99., and amazon has some for around 25 or so
But since it is an older game, just as a warning there is a chance the battery inside it is dead/almost dead.
Meaning it wont really save anymore.
But there are tutorials online that show you how to replace them.
I had to do that for my pokemon crystal when I bought it from a used gamestore where I live. After that it'll work great, and save. smile
