Seeking Anyone know of any adult games for the PS1?

[Gashka]

Recently I've installed a PS1 emulator on my phone to play some of the classic PS1 games (obviously), but I was wondering if there actually are any adult games for the PS1. I mean, surely at least a bunch were made, right? Yet, my search so far revealed little-to-nothing. At best, I came across a dating sim of some kind, and another game that I didn't bother to read the description. I realize that the Japanese porn market is different from its western counterpart (with the much stricter rules when it comes to pornographic content), but still.
Thanks in advance!
