I don't remember exactly but I think you need to use the "unlock" command with anything as the argument and then check with "monitor" to see which memory was accessed by the unlock command

Precisely! Alex's note kinda threw me off, because it sounded like you're supposed to basically disable the password check, but instead you use the password check as a pointer to the password address. So once you try a code, any code, and use "monitor", there's a line above all of the hex code-looking stuff that gives you the row and column of the password. From there you can use one of the string commands to pull up the list, store the relevant string, and then use "unlock" and throw in that stored string, and bingo! Vion is unlocked, and you even get a reward ;3
