Looking for not just the value, but more details on the cart itself. Was it a promotional giveaway/contest cart? It's been hard to find any info on it myself, the best I could find is:
http://tengokugame.f...or/famicom.html some french dude seems to be selling one? but no details on the cart. When you click the thumbnail that shows the box for it it shows the green cart. He has it listed as "Kinnikuman Muscle Tag Match Shuueisha Jidoutosho Version" with an estimated cost of 1500 euros however that seems high to me (it's way more than I paid a decade ago for sure!) and no other details. Also I tried translating the title and didn't get much out of it.
http://famicomblog.b...t-antiques.html this is odd some Japanese game show about picking the more expensive game cart and on this show it was listed as 70,000Y. It says the game was "given out as a present" and never sold.
I've kept my eye on ebay for a while of and on but can never find one.
If anyone has any info or links on this I would appreciate it. Thanks!
