/vr/ - Retro Games

After a few months break from retrogaming I went to a small event, and bought me pic related.
Mario world + DKC for €20, he wanted 25 first, hence the stickers, I offered 20, and when he declined I put the dkc down again, and he called me back.
King Arthurs World for €10, Goof Troop for €7, Buster Busts Loose was recommended by a fellow SNES fan I met over there, and got it for €5.
Secret of Mana I got from my dad for free, he got it as a fathers' day gift that many years ago, buy doesn't play anything except Snood and DX Ball any more.
The Gameboy games were €1 each, I'm curious as to what that black cartridge is, it doesn't even say "GAME" like those bootlegs usually do.
