[Tutorial] Scorpus' Sony UMD/ISO/CSO Guide

[Namer]

You can't change the USB mode if you have remotejoylite enabled...so disable it or you can't copy games

Is there different music files besides the one you mentioned(.AUD)? Because i can't find it in any of the games i have. But i find other files like that in the music/sound folders....

Is there a list of audio files that psp uses?

1st i was wondering what the diffrence is in compresion (ie lv1 > lv9)
is it just the the attempted compression or is it a difrent compresion routine
as ive tried to compress an iso and on lv9 it was the same size as lv1 compresion
2nd is there anyway to tell what you are removing (ie what the music track is)

Failed attempts using UMDgen 4.00:


- UMDGen errors when saving:
Suzumiya Haruhi no Yakosoku
Mana Khemia Student Alliance

- Can't be compressed and/or optimized:
Bleach Heat The Soul 6

Any help? Also, there are other games which I can't optimize @__@

Your games might need LBA patching.

Start with the fresh ISO.
Go to File > File List > Export. Save it as anything.
Do your optimizations.
Go to File > File List > Import. Import the previously saved file.
Save the new ISO.

In Addition, you cannot optimize CSO files directly. You need to uncompress them to ISOs before you do anything.

Thank you for the reply, however, I apologize for not specifying my PSP specs, here it is:

CFW 5.00 m33-6 + 1.50 Kernel

How about games (ISO) that errors the UMDgen? And, is it advisable to directly save ISO games to CSO when optimizing it?

No, nvm, I got it working, I used PSP ISO converter instead, it's better than UMDgen when it comes to comrpression; less CPU usage, more compressed
