How to implement DE0 SDRAM as 2-port RAM

Sure. For right now, as a first step, I'm just receiving video from a board camera (ov7670), storing it in a 2-port ram that is being used as a frame buffer (but is using the extremely limited FPGA memory). At the same time the VGA entity is pulling the pixel data from that frame buffer when it needs it and displaying it on a monitor. That's it. Really simple but I need to use SDRAM. I can only store a 160x120 frame with this limited FPGA memory. I don't mind going through a QSYS tutorial to build what I need but it sure seems like I don't need NiosII nor do I need JTAG...
