I'll do my best to condense this post. I apologize in advance if this runs long.
It was believed by many 2600 gamers that the score of 60,960 on Pole Position was improbable. Scott Stilphen of Atari Compendium noted there is a photo of such a run (by Jeff Adkins), and Twin Galaxies (TG) lists the 60,960 score by Frankie Cardulla on their leaderboard (but no photo or video).
Last week, on January 11, 2021, GregDeg posted a run of 60,960 on Stella. You can view his record run here. It's the first such run recorded on digital video (to the best of my knowledge). If you view the comments, then you'll read a comment from "LightBlue2222" stating he surpassed 63,000. In fact, LightBlue2222 posted a score of 63,260 on January 19, 2021 (yesterday) and that entire run with commentary can be viewed here.
I did a little online research and found this thread on AtariAge. The thread, which started in 2014, does feature a few downloadable hacks of Pole Position though most appear to be cosmetic in nature. (I do have to review the thread more thoroughly.)
So, with all that said, does anyone here know if a score of 62,360 is possible? Or did LightBlue222 purchase a hacked cartridge? Any context is appreciated.
