3.) Dragster Dispute - We have been following all of the discussion as well as all the various TAS analysis videos and we are maintaining a complete awareness regarding the overall issue.
We are quite aware that there are many in the community who have personally decided that a 5.51 is not possible based on all the presented code analysis evidence.
Our 3rd party investigation is still in process of reasonably eliminating the possibility of a repeatable 5.51 on Atari 2600 hardware. This involves looking directly at the memory, CPU and other activity inside different functioning Atari 2600 hardware configurations with Dragster carts inserted and executing continuous "targeted" brute force inputs via microcontroller based on results read in active memory.
To access the raw chip information and tap the various buses inside an active Atari 2600 has required the creation of very specialized interfaces with lots of trial and error, but recently some progress has been made and they are slowly getting to a workable scenario that will allow them to completely get to the bottom of this important issue.
They are seeking some specific things:
a.) Is a 5.51 possible on Atari 2600 hardware and is it repeatable on any Atari?
b.) If it is possible, how is it possible? Why does independent code analysis suggest that it isn't? What exactly is the difference (if any) that actual Atari hardware is making?
The efforts and set up is being designed to answer these specific questions.
