Only? Apart from "Plug in dusty old cartridges, CRT TVs, datasettes, or disk drives - it all works" and "128MB DDR2 RAM (16 MB system, 16 MB REU, 16 MB GeoRAM (soon), remaining MB RAM Disk)" where I assume the RAM disk fits into the "Wi-Fi game transfer" as a destination but that is just a guess from my side.

Or usb.
