It's moments like these that I really regret being a stupid teenager and selling all my shit for gas money. The only gaming related part of my childhood I still have is an n64 memory card that I found in a box somewhere.
I sold some and had many stolen. My entire NES collection was stolen from me. It has taken significant time and effort to replace my games.

Lucky for me i had the foresight to hide a few of my favorites like S. Metroid and CT.
This has been really painful rebuying things I lost so the fact that my Metroid and Chrono Trigger saves were still there brought me a lot of joy.
