This is pretty cool.
Many years ago there was a patch for
Akumajou Densetsu that basically ripped the English text from
Castlevania III and put it into the game. Awhile later, somebody else did an actual translation, which features some pretty cool story details in the intro like the Pope searching high and low for the Belmonts. (Is that in the Japanese text?) The only trouble is it doesn't use the localized names, so instead you have Ralph Belmond instead of Trevor Belmont. There's also a goofy-ass Engrish logo (as seen
here).
Now, there's a fix to that hack, which keeps the name Trevor Belmont and also adds its own interesting
Castlevania III: Dracula's Curse logo.
