Response from Jonathan: Thomas,

Unfortunately we are not sure whether your original Big Buck Hunter can be upgraded to Shooters Challenge or other versions such as Call Of The Wild. We know that there were different versions made of the Big Buck Hunter motherboard (some red, some green). From our research, we believe the green boards can be upgraded. We are not sure about the red boards. If you have a version that can be upgraded, you will need the proper boot eprom, a hard drive with the image and the proper security chip for the new Big Buck Hunter version you want to run. There was a user on KLOV (ToplessZ) that was offering upgrades for green boards at one time. You might try contacting him at this link to see if they are still available: http://forums.arcade-museum.com/showthread.php?t=283240. You might also try contacting Incredible Technologies at itsgames.com to see if they have any additional information that might help you out.

Hope that helps. Thank you for your question and good luck with your future repairs.
