The zodiac can do much less than the gp32 can do. However, in a year or two it has the potential to emulate systems better than the gp32, but at the moment it is a much worse alternative than the gp32 (software-wise). And it costs three times as much. I'm waiting for a system powerful enough to emulate the gba, psx and amiga before I would consider buying it. Zodiac is far from being that system.
