I am using a combination of
https://www.undertow.club/threads/phantasy-star-online-2-ngs-lewd-mods.3015/post-231312 for the body and
https://pso2mod.com/dick-accessory/ for the actual dick and that one still seems to be working.
If you are having trouble, are you by any chance playing on the NA version? There have been mods which needed to go into either
just win32,
just win32na or
both (NA is kind of a mess modding-wise), so try around with that.
If you want to exchange the item, look up the ice archive name of whatever you want it to replace instead on
and unpack it, as well as the dick mod. It should have an aqn file, an aqp, (maybe, but probably) an aqm and a few dds files in the resulting folder. Rename the aqn, aqp and aqm from the dick to the names you see in the one you wanna replace and copy them over. Copy the dick dds files
with their original names and copy them into the replacement accessory, too. Repack the replacement and put it back into win32.
... at least, thats how it probably works. I have never
swapped an accessory, only made mods from scratch, so dont quote me on the exact statements of what to rename, but after scrolling through the files in a hex editor, what i just typed should be
probably mostly correct.
