So, I went through Redump and there's a user named MajorPBX who has dumped virtually every disc that wasn't available since I last checked besides the WWE XI8 disc (including the Naruto 4 tournament disc!). I should really get on that before they beat me to it lol. I had the SSX Tricky and 2002 FIFA disc before they were dumped. I also really like Naruto 4 My Naruto Collection disc with the original winner's letter is one of my favorite items in my collection. I have memory card stickers from Naruto 3 tournaments so there is for sure a Naruto 3 tournament disc out there. If you would like to see those let me know, I have a lot of interesting stuff that's likely never been seen before. For documentary purposes, here is some more information about the Naruto Collection "CIB":
Sticker set that comes with the disc
Winner's letter from V Power
Yep, this is the right disc! Great find on Mercari! I will pass at this time but that's genuinely a really good price for anyone who is interested. Hoping it's someone who is not a reseller but someone who cares about that series and/or the history of that disc.
I did a cursory glance through Redump and here are some others that are currently not listed on this thread but of interest:
http://redump.org/disc/81866/ - Disney Magical Park - Mentioned this before, saw it listed once for around ~$400 once
http://redump.org/disc/81869/ - PN03 Really cool that PN03 has both a PAL and a JP demo disc! I believe that's the only game like that. Reminds me of Doshin or V Rally 3. Never seen this disc before!
http://redump.org/disc/81848/ - Yugioh Falsebound Kingdom saw this on YAJ for like $1,100 or so. Not sure if it sold or what happened.
@MegaMan52@drxandy If you were wondering, this is what a CIB Kirby Hori memory card looks like
Here's one with the packaging on and with the plastic case included.
I took the plastic packaging off the front for the first picture but it easily attaches back on. This is one of my favorite pieces of my collection If you give me like a week I will find the guide that Zelda card comes from, just can't remember off the top of my head.
