Some of you guys are being rediculaous about this. The game is clearly a bootleg. If you guys honestly believe that any game that isn't made up of eproms is authentic, maybe you need to check all the carts in your collection again. Seriously, It's not like everyone Hong Kong is some piss poor savage running around waving sticks. Real factories exist there you know, and to assume that every bootleg producing company is some sweatshop that contains no real machinery and only handtools is nothing more than a non thought-out illusion. Half the electronics in your house were probably manufactured in Hong Kong, so what makes you think that they could manufacture pretty much everything under the sun, but not maskroms? Once again, the bottom line is, if you don't see officially used chips in your cartridge, then it isn't an official cartridge.
