Gaming Shrinking the size of psx game

[Qagenn]

is there a way to shrink the size of a psx even further than .pbp

I have suikoden and the file size is 350~ mb and I want it to be 150~mb without ripping the audio completely.

I found a compressed version which was 40~mb but it had no audio at all

eboot.pbp (whether for PS1 or PSP games) is already a trimmed format, and while creating a PS1 eboot you can configure the amount of compression (and going above 1-3 out of 9 rarely pays off - extra processing power for maybe a handful of MBs), but definitely it won't turn 350 into 150 unless the former was at compression level 0
