Got a need for nostalgia. Last game was MGS4. Before that, it was THPS1&2.

Damn. This a little meme reminder that any savings i have towards retirement could disappear in an instant.

Not sure if you are looking for some deep explanation. I can’t tell based on the question. Anyway, animal crossing for the game cube has (had?) collectible items such as NES games, though they could only be played if you also had a console item. Basically, you could play NES games in animal crossing. The post seems to be mainly about hacking this part of the game to allow playing other games. As to why it has the ability? Idk? Because developers decided to include NES emulator as part of the ROM.

Wait, you are telling people had discussion in Usenet? No way!
