Yup.
Let's assume--no, let's not even assume, let's
acknowledge the canonical fact that Kirito is something of a prodigy who has extensively studied not just programming in general, but the APIs and previous applications written for the NerveGear hardware and the books written by the person who designed SAO.
Now he's been given elevated privileges at a GM console with an interface that it's entirely possible he's either studied from Kayaba's books or actually used before.
So let's say Kirito types something like this:
Code:
> show -f system.entities|grep yui
1 line(s) matched: //sys/ents/admin/yui.entdata
> copy -r -s //sys/ents/admin/yui.entdata -t //self/local/yuibackup
1 folder(s) copied recursively to local storage.
> gm.spawnGameObjectAtPlayer -u -n "Yui's Heart" -t player.Kirito -a //res/items/appearance/bluecrystalheart.pak -i //self/local/yuibackup
Usable item [Yui's Heart] spawned successfully at player.Kirito - linked to //self/local/yuibackup
Takes all of five seconds. And then he gets forcibly logged out.
Problem solved.
Note: I pulled all of that out of the nether in about 5 minutes based on 20+ years working with command line systems. I would have so much respect for anime/movie producers if they'd just call up one of their hacker/geek friends and ask them to make up some convincing-looking actual commands for what they're trying to portray rather than this lazy Matrix stuff.
