: Let's say you are playing a board game. You get a rule book, and in it are
: the possible actions you can take as a player, and what results from those
: actions and how those interact with other actions. The rulebook lays out
: the game for you and tells you what you can and can't do.

: Cheating would be making a move that is not permitted.

: However, you may find a series of permitted rules that interact in strange
: and powerful ways. As long as everything you do is permitted by the rules,
: you are not cheating.

: Video games are no different, except that instead of the rule book telling
: you what you can and can't do, the game code does. Provided all you are
: doing is pressing buttons and doing actions the game allows, you aren't
: cheating.

: I'd say the only exception I can think of is exploiting overflows to
: reprogram the game on the fly (such as in the Mario World snake / pong
: tas), since at that point the hardware is executing YOUR code, not the
: designer's. Same goes for making the game jump to memory addresses that
: were not possible with the original code.

Well based on your example, we can all expect BXR and the other button glitches to be laid out in the Halo 2 manual then (seeing as how they're possible actions).

Halo 2 has been mentioned in the same sentence as fighting games when talking about button combos. Yet a fighting game will lay out any and all combos in the help section/manual. Halo 2 does not (and I'm willing to bet won't) come November.
