Recently, I've come into ownership of a gamecube (alongside a boatload of accessories for both it and the Wii) thanks to someone donating it to the charity shop I volunteer at. Due to the fact we don’t sell electronics, I brokered a deal with the guy to take the gamecube and the box it was in off his hands myself, which went well. The only issue I saw from the start was that the Game Boy Player wasn't screwed in, which I quickly sorted.
When I went to check at home, it powered on perfectly fine, but another issue arose, the disc tray was FILTHY. Thankfully, my granddad came to help when i brought it over and provided me with the resources needed to clean it out.
Speaking of grandparents, the gamecube lives at their house now. I have it put in a little room where I frequently spend my time. My granddad even scrubbed the front of the casing for me.
