I did about 10 mii plaza related memory dumps over the weekend.
I'm not going to have a chance to comb through them for a few days though.
Here's my data logs for the first five dumps alone:
0.Plaza. No Games played, people at the gate, 4 tickets. StreetPass hits:14, sheik mask
1.Plaza. Quest played, people at the gate, 4 tickets. StreetPass hits:14, sheik mask
2.Puzzle. Pieces collected. Piece 39 of Kirby triple. Piece 38 of Kirby triple.
3.Plaza. Puzzle/Quest played, people at the gate, 3 tickets. StreetPass hits:14, falcon mask
4.Battle. Visitors waiting, allied soldiers 21320, conquered 2, 21 v.soldiers
5.Battle. Visitors greeted, allied soldiers 31534, conquered 2, achievement earned. Castle of lvl 1
ARCodes I'm hoping to produce from these 5 dumps are things like modify number of plaza tickets, number of street passes (for instant unlock of tag related achievements) and maybe
unlock all hats (but I don't think I have enough data for this yet).
I'm also hoping to make a complete all puzzles code or failing that, one that resets the "puzzles collected" flag which would allow you to collect and recollect puzzle pieces from the same visitors, which would make puzzle completion easier.
Codes related specifically to the "war" DLC game would be things like modifying the number of allied troops, your castle's "level", number of troops contributed by visitors etc...
Resetting "is completed" and similar flags is one of my main goals, as it would allow repeated playing of the games using the same visitors.
I'll make codes to max anything measured by a number (max money, troops, HP etc..), these codes are easy and only require a couple of data samples.
Things that will take more time (and data samples) to produce results are things like unlock all hats/achievements/puzzles, because they're not measured by visible numbers. I also don't know whether a single value is used or a series of simple 0/1 on/off switches or FF etc...
Some codes may be better suited to being used as a plugin for NTR2 as opposed to the ARCode format. I'll get a better idea of what's achievable once I look over the data this week sometime.
