Very detailed. The only thing not mentioned is, that the hoax will be
revealed after the "VIC too hot" messages beeps xx-times (Forgot the
value, but it was way too large :)).

To be very precise, it is a 25 7/8 line, but it can be done as a full 26th
line. This trick is pretty straightforward, start displaying a pic at
rasterline $30 and you will be able to do a badline on the very last line
of the pic, which gives you some additional lines. Of course, the badline
must restart the internal VIC-counters, so it has to be a few cycles
before you'd change $d011 for displaying FLI.

I developed the idea while doing the 64Hz-IFLI-viewer for the C128, cause
I had some GFX-garbage in the lower border. As I hadn't seen such a part
till then, but just a 26th line alone may be boring, I added the weirdest
text my mind could come up with. Well, it may also have been a late
revenge for all these people who fooled me with such texts ;) I never
realized some people would actually open their commies and try! I feel
kind of sorry for them, I hope you don't mind.
Of course, I was not the first to do that, I was at least 12 years too
late, but hey, I found it all on my own. And this kind of coding makes the
C64 RULE! :)))
