Rikthoff (talk) The issue date is definitely off. Can anyone fix this?

Wait until he finds out they're codes for that old saving system. 21:42, 3 June 2013 (UTC)

Or perhaps the Black Hat is answering the question but in an obscure way. The addresses might be pointing to the locations where the game keeps its important information (such as the score count or the level), so it can be cheated by changing the data at these locations.

Ok I understand that it is etiquette not to edit other people's comments, but he wanted to underline 'is' so I did it for him :) Beanie (talk) 11:04, 17 March 2021 (UTC)

The problem with 0x-1 is not that it's missing digits, it's that the memory in the computer is represented as a closed loop. So if you try to go back to the cell "before the first cell", you will really access the last cell, 0x-1 really equals to 0xFFFFFFFF in the 32-bit address space. Evidently, Cueball had found a way around this only it didn't quite work out. (People deeply interested in the workings of the pointers should also read about the memory protection modes and alignment requirements, both of which might interfere with reading from the address 0xFFFFFFFF.) 00:33, 28 January 2014 (UTC)

Cueball could be playing a card game (e.g. Solitaire), and Black Hat could be telling him to play the Ace. In a rather obscure way, though. -- 17:46, 25 August 2014 (UTC)

Hidden message?

The three pointers spell, in ASCII:


Does this make any sense? The last line looks like German. -- 07:01, 8 October 2014 (UTC)

The last one is German. It means "I". (talk) (please sign your comments with ~~~~)

No, you got the ASCII wrong. 73 is "s", not "I":

I think that the title text is a Matrix reference. All humans are- being kept in a dream world so that their (erm, our) comatose cadavers can be used to generate electricity? RedHatGuy68 (talk) 02:55, 18 October 2015 (UTC)

Regarding the last letters, in the TASBot stuff I lead we often refer to the act of taking complete control of a game as an Arbitrary Code Execution, or an ACE. However, the term was somewhat obscure at the time this comic was released (TASBot content didn't become well known until 2015) so I don't think it's likely enough to put in the main explanation. 20:34, 2 November 2017 (UTC)dwangoAC

I moved the title text explanation to the main one. Seems to make more sense that way. Dontknow (talk) 23:35, 17 April 2017 (UTC)

The pointers are different in xkcd: Volume 0. I added that in along with a trivia section. 03:35, 9 October 2020 (UTC)

0xCD is not an ASCII character as it has the high bit. 16:47, 10 April 2022 (UTC)
I believe the ASCII converter used didn't discard the high bit and just converted it byte by byte (I believe this is why Í appeared, given that Í corresponds to Í). 14:37, 8 December 2022 (UTC)
