hey grumble i stopped for once to take a look and your version has alot more legal info than my retail cover does. lol.
the part being blocked by a "United video sticker" is the "This seal is your assurance that Nintendo® has approved the quality of this product. Always look for this seal when buying games and accessories to ensure complete compatibility with your Nintendo Entertainment System"
pal version sez also "Distrubuted by Ocean Europe LTD, 6 Central Street, Manchester M2 5NS, England."
above barcode just sez "Made in Japan, GAME PAK (NES-GP)"
bottom sez "Recommended for ages 8 to adult"
and i just peeled back sticker and it sez
"Ocean is a registered trademark"
"Nintendo and Nintendo Entertainment System are trademarks of Nintendo"
Also below the 3rd pic it sez "TM & © 1991 Taito Corportation"
I hope all that info helps and you can make another excellent cover i can use on my cases! Your a legend <3
