FPU is theoretically possible in these FPGA boards, but no one has yet to dedicate the effort to build one. I think it's a lot of work. For FPU, you need to get the Apollo or use real hardware.
Cool thing Is that internet Is up and running even if One plays a game. So I can download something from internet while playing a game!! You dont Need to turn off network to use whdload games.
Ok, this is a big mist/mistica. Why do you not improve instead just change to ITX the board, with more connections, like IDE, second SD card, etc. I have one SIDI FPGA using the same minimig core, and the results are the same. I miss in this board one IDE for plug a real HD, CD-rom or Flash card adaptor and a second SD slot.
