New version supports all D2C2/D2E chipset versions, including D1A, via a 9-wire installation
Original version requires a 15-wire installation (4 additional wires required for region override)
Supports all regions, configurable via jumpers
Direct boot of Wii and Gamecube original, import, and backup discs
Suberb media compability; works with most writeable DVD media, including DL, and factory made 'silvers'
Works with most 'problem' titles such as SMG and SSBB
Integrated Audiostreaming fix for GC games
Advanced error detection makes d2pro less susceptible to lockups and freezes compared to other low-wirecount chips
Fully updateable via external USB programmer
Rock solid performance with 1.5V FPGA core and high quality components
 

While every effort has been taken to ensure that d2pro is compatible with a broad range of media and drives there is no guarantee that any given media or game will work on a specific drive.
There are a number of factors beyond the scope of d2pro functionality that affects media compability, such as the laser diode and other internal circuitry in the dvd drive.
