wow that looks incredibly fake. If it were a true old nes castlevania game it would would have the old font. If this guy were trying to pass it off as a classic nes game you think he would have at least got the font right.

Just read the rest of the posts. I love looking for and playing altered/souped up versions of the original cv if it weren't so expensive I'd pick this up as it appears the coder did a really good job.

Still, how do you get a homebrew into a NES cartridge??
It's actually incredibly easy. All's you have to do is erase the game that's on one and code the new one you want to replace it with on there.
