Nothing big...your enthusiasm about the console far outweighs any pedantic discrepancies that an old-console fanboy like myself might notice. Since you asked, though, there are really only two corrections I would suggest: the Gorf and Wizard of Wor coin-ops came out a couple of years after the Bally Professional Arcade did, whereas you give the impression that they already existed when the console appeared; and the Atari 2600 actually has 128 bytes of RAM. In the latter case, I think you actually meant to say that, rather than saying K. The structure of your sentence indicates that it was just the sort of verbal typo that we all make from time to time. So: no big deal! I'm just glad to see someone making high-quality Bally console videos.
