Castlevania: The Dracula X Chronicles review at Gamespot.

"Castlevania: The Dracula X Chronicles for the PSP collects two (or three, depending on how you look at it) separate installments of Konami's Castlevania series together on a single disc. The formerly Japanese-exclusive Dracula X: Rondo of Blood represents two of the three games on the disc. You can play this old-school classic in its remade form, which features 3D graphics and newly recorded music and voice acting. Alternately, you can play it just as PC Engine CD-ROM owners experienced it back in 1993, with its original music and 2D graphics, as well as your choice of the original Japanese dialogue or a new English translation. The third game on the disc is a rendition of Castlevania: Symphony of the Night that boasts some miscellaneous improvements over the PlayStation and Xbox 360 versions you might already be familiar with."
