I was under the understand that DVDs are 2 discs stuck toghther and so maybe that DVD of Cel Damage has some how been seperated. If you look at a disc carefully from the side you will see the 2 layers of plastic
I bet that cel damage game has been resurfaced down to the data layer. Explains the thinness. With Each resurface, at least to my knowledge, takes a layer of polycarbonate, and I believe most discs only have 3 layers before you get to the aluminium layer (The data layer) which I think has also been resurfaced off which would explain why it doesn't work
You also gotta love the irony of how sometimes that the crappiest games are packaged awesome .. and then great ones aren't package well at all ... like all together loose in an envelope. It's like luck of the draw sometimes with some sellers.
I've watched a few of your videos now and want to let you know some things that stood out to me. One thing on this video is you skipped out on Dance Dance Revolution because you don't have a mat. You can play the game with the controller. you can use the d pad and the buttons simultaneously and it's still really fun. Another video I noticed you decided to keep a newer edition of a ps2 game and taking notice of all the case and manual but you missed the fact that the one you decided to save wasn't a ps2 case and had no memory card holder. There's more things I noticed but, I'm just pointing out little things I've noticed to help you slow down and consider all things.
Fun vid! Rally Sport Challenge ohh the memories one of my fav games from back in that day that I finished to the end (I had bought the original Xbox at launch with Halo, NHL Hitz lol and a spare controller)
