Do PICs support this? If not, or if its not enabled by chance, you can try to do a read-back of both chips Flash to get an idea of what they're doing. Of course IFI might show up on your doorstep with one of those MIB flashy-things...

I beilive some PICs have it but not all. I am not completely sure but I have heard of people locking down some bits so they cant be changed.

I wouldnt feel to back about bricking them if i could buy the vex controller seprately since it wouldnt be to expensive. But I cant find em online or on ebay.
