Link is dead for "Read more about registers and flags here"

[gtsherman]

The link to http://www.obelisk.me.uk/6502/registers.html seems to be dead.

The easiest solution might be to use the Wayback Machine link instead: https://web.archive.org/web/20210626024532/http://www.obelisk.me.uk/6502/registers.html

I just noticed this and was about to make an issue for it :-)
