Local shops are always > for vintage. There's some nerd nerdier than the nerdiest nerd you know that owns an old check cashing building in some dingy shopping center full of vintage games.

+ supporting your local business is always good mannered fun.

Have you tried gamegavel?

i have a copy of just about every nes game made that's on disc and can only be played on the dreamcast... ofc my dog chewed up the cord to it and i can't play it anymore ...can sum1 direct me to a site or something where i can buy a new one?

for dreamcast games i just get the ISO and burn it to a CD-R.

Thats all you have to do and it will play on a dreamcast just like the official game.

For games that i actually want to collect like n64/GB/GBA i go to 3bay
