This is a *fascinating* concept for games studies - "quotes" of a game that don't just show you a clip of gameplay, but actually let you take control and try it out. It trims the ROM down to only what's needed to run the quote, so this might even pass a fair dealing/fair use test in court if it came down to it - just like quoting a passage of text, or a clip of a movie.

Create and share playable quotes of Game Boy games

A playable quote is a durable, delimited reference to a specific moment in a game along with a reference recording of how that moment can play out.

@misty Interesting. I wonder how it would work with a game like megaman -- presumably if you tried to switch to any weapon that wasn't in use during the recording, you would go outside the bounds of the quote, assuming that there was unique code/data attached to each weapon and that would not be preserved in the save state (I assume the code is all in ROM but I'm not sure about the data, not familiar with game boy internals).
@joseph_garvin @misty for the version of quotes that we have on tenmile.quote.games, you’d get reset when you tried an unquoted weapon. If you let the emulation keep running however … strange things happen. The game might move past the gun, or may behave oddly. It depends on what it does when it reads or executed 0x00 instead of what it expected
@jpf @joseph_garvin @misty So I just tried the quote of Tetris on tenmile.quote.games. The description says, "You can clear a few lines at a time, but you can't have the satisfaction of completing a Tetris (clearing 4 lines at once) because that's not included in the quote." But when I tried it, I could indeed clear four lines -- and then the game would reset, which is kind of even *more* of a reward, unless you were aiming for a high score, I guess.
@lindsey that’s a very fair observation. I suppose we should update it to say that you can’t continue playing after competing a Tetris.
