Bring up the Quick Menu, and from there you can access the Pose Menu, and it will show the toggle for emote or hand pose modes

Hand poses only work with NGS bodies, you may want to make sure you are using the right outfit or CAST parts. Also there are no chat command for hand poses yet (I looked it up since I have a couple so far), so you have to use the emote menu.
Highlight the emote you want to run, then switch to hand pose mode and set that, the emote and hand pose should activate at the same time. (On a keyboard the toggle between emote mode and hand pose mode is the "R" key, I don't know what it would be for a controller)
I think the music disk only has the English version, just like a bunch of other music disks that only have one track.
All my PSO2 stuff actuality got better with the NGS update from the higher texture detail, bust as of right now there is much in the way of male CAST parts for my main character, but I got one decent NGS outfit for my alt so far (The rest of her stuff is PSO2 outfits).
I say ditch the pay walls since will be more of a hassle for F2Ps, but for the story mode parts, you just need to comeplete it to a certain point, NGS already does this with a number of functions.
But we desperately need a way to get rid of the bots, sometimes you get two or three of them spamming the same scam site in an area, and its getting worse since not only are there block hopper bots, now more of them are being hidden all over the main city.
