Hacking Slow sound in EBOOTs

[SaddQ]

I recently blew new life into my PSP-3000s by hacking them using LME v6.61.
Wanting to play some rare PSX EBOOTs that I couldn't find an already converted version of, I created quite a few using PSX2PSP, with compression set to 2.

A few games however, have incredibly slow audio, like it's playing at half speed. Gameplay seems like normal though.

Two of those games are International Superstar Soccer Deluxe (PAL) and Jikkyou Oshaberi Parodius (J).
Their audio is severely affected.
Other custom EBOOTs don't have the same problem and play and sound as normal.

I'm 99% sure the rate of compression has nothing to do with it.

Maybe the Compression it too high,please try 1-2 or better 0.

Thank you.

Thank you.

Compression level 0 results in a black screen. I use level 2.
There must be something about how the audio in some games works, compared to others.

As mentioned before, two of the games I found have this issue are ISS Deluxe and Oshaberi Parodius: Forever With Me. Both are older games and both might use a different audio format. Something like Redbook? I don't have a clue about it.

Tested both Eboots (from PSX Games) on the PSP-1004 with 6.61 PROMOD C2p.

Can confirm,these 2 Games (Uncompressed) have this Issue.I did not find them on any Compatiblitly List for POPS Loader so I think it is as it is - not working correctly.
Tried different POPS Loader Version,raised the PSP´s Game Clock,raised Reading Speed....

There are also "no custom Eboots" in the Internet from these 2 Games.

Thank you.

It seems to be a problem with the audio only though. Any ideas if a fix for that is possible? I read something about older PSX games using a different audio format compared to newer ones and therefore not running correctly without some additional hocus-pocus.
