The double up flaw is driven by the bill feeder issue. If you were not able to insert a bill, which is the key to being able to change the denomination, then there would be no bug. So the "fix" had to focus on that.
Axel doesn't really know which generation machine he was playing, and I never had any idea about certain generations of machines having this flaw when I played it. I ran across plenty of possible machines back then that didn't work. The fact that he played a machine that lit up after a winning hand and before choosing to double up or not doesn't surprise me. But if you're saying that IGT did not send out new programs that did not 100% conform to the specs the machines were supposed to be running at, I'd call bs on that.
This bit of information about the bill feeder being the key because it allowed one to change denomination is another piece of information that adds to Rob's credibility. I had no idea why the bill feeder was key until Rob explained it here. I dont' think that bit of information was published anywhere or I would have recalled reading it.
FYI, I knew this information before Rob had said anything, so it wasn't a complete secret. If you go back, you can see I mention something about this before however I may have disguised the exact thing I was talking about. I have been told by someone in the know that this information was public, but they were not 100% sure, they were just very sure.
"Cant say for sure but I'm sure." LOL! Track these people down and have them post something here.
