Wow that article was very in depth. I love watching people slowly dissect something, then stumble on some big "AH HAH!" like the debug out on the Tengen chip
Did kevtris release the PIC code for the Ciclone publicly or are you running custom code on the Ciclones you sell on your site bunnyboy? I read somewhere that he coded Ciclone for the PIC 18F452, but the Ciclones supported by your Repropak look like the 12F series (I'm guessing because the 12F are the only 8 leg PICs I've worked with)
Overall a very impressive hack and a great tutorial, I'm amazed hong kong carts used CIC stunners for so long!
