Hacking ISO or CSO?

[Just Another Gamer]

I know that CSO is slower but I was curious to see which is better for graphics, video and audio and which format I should be using.

Game graphics aren't affected. Audio and video of cutscenes would only be affected if they were resampled (it's an option).

There's other options, like ripping out the update files (useless on CFW), and various compression levels, etc, so you can't really tell what's been modified in a CSO unless you did it yourself.

What about the audio during gameplay?

I normally do level 9 compression since the extra few second loading times don't bother me much but I wasn't ever really sure if that affects the audio or not during gameplay since I sometimes get some music lag.

Sound effects and RPG soundtracks and junk tend to be in archives and custom formats that wouldn't be touched, but games that have a bunch of MP3s or whatever laying around (sports games with pop/rock music, etc.) would likely be hit if the person who compressed it chose to lossily-compress the audio.

The compression level is just about the lossless compression IIRC, the stuff that resamples the audio/video are separate options in the compressors.

Music lag would be access lag which would be caused by high-level compression.

So a lower to no compression will reduce access lag what level would be reasonable to reduce the size of the ISO while still getting the same audio quality?

I haven't done much lately, but if I remember right ~4 seemed best.

I'll try it and see how it is. Thanks for the assist.
