please read: https://www.ngemu.com/threads/pcsxr-pgxp.186369/page-50#post-2728237is that worse than the default ones?
in short, you will probably need at least the spuPeopsDSound109.dll version for some games and you will need spuPeopsSound_110b_svn7.dll for others. I can't say whether with both of them the PSX game library can be played.
I use 1.09 by default, maybe most jrpg games need 1.10b svn 7, I don't have the habit of playing them, I believe they were mentioned in the 1.10b changelogs. [I may be wrong!]
