MiSTer is a port of well known MiST project to a larger FPGA and faster ARM. MiSTer provides modern video output through HDMI (VGA and analog audio are still available on daughter board). It's based on Terasic DE10-nano board. Here are some improvement over the MiST board:

Altera Cyclone V SE FPGA with 110,000LE (41,500ALM) and 5,570Kbit of Block RAM.
ARM Cortex A9 dual-core CPU at 800MHz.
HDMI video and audio allowing connect to any modern monitor/TV.
DDR3 1GB available for both ARM and FPGA.
High speed ARM<->FPGA interconnect due to both are in the same chip.
Linux on ARM provides support for many I/O devices and file systems.
32Mb SDRAM memory.
VGA output.

Include Terasic DE10-nano, 7 ports USB hub, IO board, extra slim SDRAM, microSD 8Gb, acrylic case and PSU.
