I posted this over on DP. but I'll repost it here: Dream and I both have this same proto, though mine are just loose chips (for the moment). He traded a Stadium Events cart for his and I paid $350 for mine. Both originally were from Vixenkit on DP, they were sold to MB7241, then later sold to Jason and myself. Both of ours have the exact same writing and date as yours. Now you don't have to be worried about people selling copies of the data I just purchased a blank TKEPROM-02 board as well (it was a Trolls in crazyland proto, but someone had long removed those chips), so I'll have my chips populated on a board soon enough. Very cool that there are at least 3 of these out there, I hadn't seen this one before. How long have you had it? Got any other cool NES stuff kicking around This game is exactly the same as the PAL game with the same name, only modified for the region.
Oh, and it's odd that your board has a socketed and exposed WRAM chip as this game doesn't need it. It's often that these boards are "over" populated though, as seen with the battery that is also unnecessary. I'm assuming the company was using this board to test other games as there wouldn't be any other reason to cut a hole in the cart shell to expose that part.
I'm guessing it's not available for free if you paid $350 I hope I don't piss people off when I dump it in a bit.
You won't be pissing off me, I was planning on dumping it and including it as part of my monthly free proto ROM release on NA, but I've been waiting to get a board for it so I could dump it with my copy NES. My EPROM programmer doesn't like the chips (27c301's) otherwise I would have dumped it and released it months ago. I release 99% of my stuff for free regardless of what I paid for it, doesn't mean much to me as I'm not selling any of my NES stuff anytime soon. You have any other NES protos? I got an extra few hundred bucks kicking around if you were looking to sell anything.
