@MrWunderful - The cost would be around $120 USD shipped. The seller is in Japan. Since you have some experience with these carts, do you know if they can be played in an NTSC NES console, or something like the AVS/Analogue NT? The form factor looks identical to an NTSC NES cart, but I can’t find a definitive answer online as to whether they can be played as such on a US console.
