It means he told him to hold on to his wallet.
To bid = to command or to direct. Bade = past tense of bid. Suffix "-est" is applied to second-person singular verb conjugations.
Hence, "thou badest".
Here's the thing: until I did this project, it had been been a long time since I'd read or given thought to anything written in such old-fashioned language, but that style of expression was kind of seared into my brain as a kid due to being required to read the King James every week. I played Chrono Trigger for the first time a few months ago, and I found that I liked the idea of Frog's speech style, but my heart sank almost immediately when his very first line of dialog came out mangled due to simple grammatical errors. Fixing that was actually going to be my first foray into this kind of thing, but then I came across Mato's FF6 comparison and got sidetracked by doing this instead.
All I really wanted to do with these games was just to play them, not hack them. But as the comparison showed there were so many translation problems I hadn't known about, I found that I had the interest and motivation to do something about them, and a level of impartiality about the script due to having no longstanding attachment to any pre-existing version. Recall that in the first post I mentioned that up until a few weeks ago, I had no plans to release this publicly at all: it was begun as something solely for my own benefit. I only came around to the idea of releasing it when I saw various people online wishing there were a version with the general sort of qualities of what I had done.
Obviously the style I used for Cyan is a bit removed from normal present day speech. Hence why I wrote a document explaining the nuances of the grammar, in the event of just this sort of confusion. I tried to keep it as clear and understandable as I could, but I'm not the sort of person to do something halfway, and I don't believe in dumbing things down and underestimating the audience. The actual amount of archaic vocabulary in this script is extremely low. The only things that are "old" are the verb conjugations, personal pronouns, a couple of words or expressions that had slightly different definitions back then, and the tendency to put the syntax of a sentence in a slightly different order. Everything else is the same. If I'd really wanted to go full-on obscure, I would have spelled the words the way they spelled them back then, too, but then almost nobody in the world (including me) would have any idea what they were saying.
Naturally, of course, anyone is welcome to play any version they want, and it's good there are options. My hope is that others will enjoy playing this, but I never had any illusions about being able to satisfy everyone.
For the breast thing, I felt it important to avoid being unnecessarily crude. 'Assets' might work, but we'll see.
