A 1GHz Cubox i-series ARM machine can hit 30fps when streaming 1080p from the Internet. Why put an FPGA on it?
I like the FPGAArcade Replay board but it would never complete with the Cubox in price.
The Replay will go for $299 and the Cubox-i1 goes for $59. The quad-core Cubox-i4Pro is $139. All we really need is a multithreaded AGA core in the emulator and AROS/ARIX will do the rest.
