It was $1.50, still didn't seem worth it, but then the seller said I could take it for $1, still made me think about it but what the heck, I got it. I left it in my car, in the sun the whole day. When I got home, I opened it, cleaned part of it and decided to take it to my parents' house to finish there, but it took a fall on the way. I took a peek and the LED had come partially off and everything inside was bent. That made me put it in the trunk and forget about it for months until I cleaned my car and put it inside a box, making me forget about it another few months.
So finally, a year and a half later, I opened the box and saw it there, no screws and all forgotten, so I decided to check it out.
Just to give you an idea of how dirty it is, here's a picture, notice the thick coat of dirt near the card and cartridge ports, I removed some dirt with my finger to make the difference more noticeable, there's also lots of lint everywhere and to top it off, the edges are entirely rusty.

Seemed like a lost cause, but I still had to give it a shot. I didn't even bother putting it back inside the casing, I just plugged everything in and crossed my fingers.

The game I tried was Ganster Town, the box has a cute picture of a kid firing a machine gun.

So here it was, the moment of truth, after all its been through, will it work?

It did! A truly amazing feat, but now, does it work with cards? The card made a scratchy sound because of all the dirt in the slot, that made me doubt that it would work.

But it works too! Both on the first try! I didn't see that coming. This poor SMS has had a very though life but its still kicking, unlike my Xbox that died on me just when I was about to beat Jet Set Radio Future, but that's a story for another day.
Now to finish cleaning it up, hoping I don't forget about it again.
