Eek, I didn't notice until I reread the post. I think he sorta messed up on the listing. I don't know if Perfect Dark's the only N64 prototype in the lot, not entirely sure, but it's probably the only one that needs the extra tool if it's not the only one. I'm pretty sure the Conker debug build is for the Xbox, but his listing's a little weird.

Sorry if this complicates things. I don't know for sure either. :\
