SN Systems has released Proview Plus for the Playstation 2 console, a postmortem debugger that works with Sony's latest development hardware (DTL-H3010*LT).
The software-based debugger communicates with the debugging console via the FireWire port, leaving both the Ethernet and USB ports availble for use by the game you are debugging. It requires either Windows 2000 or Windoes XP, a FireWire port on your computer, and the aforementioned development hardware.
Proview Plus is available for $1,000, or bundled with ProDG ($6,100) or ProDG Plus ($7,200).
