MisterFPGA has a real image problem. It just exudes "complicated". Visit the homepage and witness exposed boards and adapters shooting everywhere, along with constant talk about loading cores and updates.
SuperNT/MegaSG and RetroUSB's AVS are popular because they remove that barrier for entry. This one promises to do that, but obviously people are skeptical. The fact they want to launch without full Dreamcast capabilities and say it'll be updated later means they already put up a barrier for entry.
