MiSTER is going strong and the recent release of the excellent-but-confusingly-named MiSTER Pi [1] board has brought the cost of entry down considerably. After I do some more SD card shuffling and verify game compatibility I plan on selling my N64 and Saturn and using OEM controllers with my MiSTER Pi. Unfortunately the Altera Cyclone FPGA in it doesn't have the horsepower to run anything beyond fifth-gen systems so a new platform would be required for the Dreamcast, Gamecube, and PS2. The common refrain from FPGA enthusiasts regarding these systems is that because the hardware has many more layers of abstraction they're less dependent on cycle-accurate timing than older consoles so the juice might not be worth the squeeze as far as building HDL cores for them is concerned.

There's also the question of the huge amount of engineering effort required to recreate the more advanced platforms.
The Replay2 board should provide both a much more capable FPGA and loads of RAM bandwidth to go with it. (Finishing touches are apparently being made to the prototype board layout, and production is slated for the Spring)
And for anyone who thought FPGA gaming was a new phenomenon, work on the original Minimig FPGA recreation of the Amiga started in January 2005 - 20 years ago!
