Describe the issue

I have played through Xenosaga II multiple times over the years via my Fat PS2 using an internal hard drive and have had no issues each time I played this game. This is how I play all my games over the years. I recently decided to try playing games via SMB and have had no issues with my testing. I use a Windows 7 and Windows 10 laptop (I've tested multiple laptops and my desktop PC), have my share set up, IP settings configured on the PC, IP settings configured in OPL, and connect a normal 3 feet patch cable to the PS2 directly from the PC. All my games have played fine via SMB on all the below PS2 models, testing multiple PCs, multiple revisions of OPL. However, Xenosaga II with SMB seems to have some music slow down when I enter and exit the game menu or do a screen transition. The music slows down for a couple seconds, then returns to normal, and it's a very short slowdown. I've tested this on disc 1 and disc 2. What's odd is that cut scenes play without any issue and I don't have any FMV issues with any other games. You can quickly test this yourself by just starting a new game, you can skip the cut scenes if you want to quickly get control of the character, open and close the menu, and run back and forth to next screen by the first save point. I have also attached a save file for disc 2 where you can repeat the same issues.

I have tested all the below OPL revisions, a few different patch cables, all the below PS2 models, multiple PCs, using Mode 1 Accurate Reads, using Mode 2 Synchronous Reads, using Ethernet Link Mode Auto, using 100Mbit Full-duplex, and using 100Mbit Half-duplex. It does the same slowdown for any version of OPL, multiple PS2 models, when using SMB. I have tested all the listed models using Free MCBoot [Version 1.966] FMCB, Free MCBoot [Version 1.966] FHDB, FunTuna-FreeMcBoot-for-Fortuna_2020-08-30-(2).

I just want to confirm this issue. I have noticed it too.

Would like to corroborate, I have the same issue except I'm running Xenosaga II from the HDD in my PS2 Phat. Currently finished Disc 1 and the slowdown was most prominent during load transitions or walking from one half of a large environment to the other.

Mode 2 fixes this on 1.2.0 beta of OPL for HDD, I likely forgot to save settings but this DOES seem to be the solution. I had a ton of issues with the first two Xenosaga games that ended up being a hard drive compatibility issue (random crashes and the like), swapped drives and mode 2 works perfectly for the audio.
