what files are safe to delete from inside a freshly ripped iso file like say, metal gear solid portable ops or daxter?

[Hitokiri]

use umdgen's dummy remove or optimizer

and usually only update folder (which dummy removes)

And if a eur iso/cso the other lang files are usually safe to remove

And the:
pad.pad0
pad.pad1
pad.pad2
pad.pad3

And so on. (If you find any )
