I bought it about 2 weeks ago, and just beat the game last night. I've obtained 10 out of the game's 12 achievements. I'm still working on "Seeker" and "Belmont's Revenge".

I love this game. It worth its price.

Pros:
-Full console (Playstation) game at the price of XBLA game
-Classic gameplay, brings back my childood memories
-Enhanced graphic mode (but it's only noticeable on HD TV / monitor)
-5 different endings
-Addition of 12 achievements worth 200 points

Cons:
-Slowdown at the waterfall area
-No widescreen mode
-2 FMV from the Playstation version has been removed to keep the file size small

Just attack the gears (2 gears per room, got 2 rooms side by side), they will "click".

I mean if u using sword, just jump/walk till in front of the gears then whack them.
