How to play online on Namco Museum battle collection?

[KeithHasAPSP12356]

Hi guys,

I hope you are all well. Pls, I remember a long time ago that there was a page or room where several game servers were listed, the number of players, etc. Unfortunately, I don't remember that page. Anyway, I would like to play "Namco Museum Battle Collection" online. I've tried using the default network settings in PPSSPP, but there are never any servers or players online. I mean, I log in as a client. See if you can give me some advice.
