The OrigaChip isn't particularly easy to install as it has 15 wires (it needs more than 8 to do the extra work). But it's easier than NEO4. Madeira Games will supply it and fit it, but that will set you back £115, including the courier service. A soldering whizzo can do it if competent with 1mm tip and wire. The investment is sound if you want to play import originals.
