Here is another issue Mas. You join a forum that is dedicated to the PCE and the TG-16, yet you seem to only be here to look for games to buy. This is why Blue suggested to go to ebay if all you want is games. How about you get to know the community first. Join some discussions, ask questions about games, or what games to play ect. No you come in this group of established community members, and basically say "sell me your unwanted games because i want to play them, but they need to have the plastic case and paper instructions because somehow i can't play the games without those"?
Can you see why people who have been on this forum for years would see that as suspect. Blue, and many other have been on this forum for a long time, and far to often people with the same mindset as you come along, try to buy things from members, and then just vanish. No one here wants to deal with that shit, and no one here is going to have open arms to someone who's first post consist of asking for games.
