Arcana Heart 2 is one of those mysterious arcade games that got a recent PS2 port. The port was pretty bad: the sprites looked like ass, the framerate dipped below 10FPS at times and so forth. It's pretty damning considering that the game is a 2D fighting game and that for some mysterious reason the game runs far better emulated... on a PC (solid 60fps, by the way).
Saints Row 2 on the PC is pretty bad too but it has been mentioned already.

Every Quake port ever made. The first two were ported to consoles, and failed because people didn't know how to make FPSes work on a console yet.
You played/seen the Sega Saturn version of the original Quake? It's hilarious since it doesn't even use the Quake engine.
