Metal Gear Solid: Peace Walker

[Kabuto_Kun]

If you have played at Peace Walker before, you may be aware that the game makes use of DATA INSTALL, a very common feature in the "last wave" of PSP games. It was used to minimize the loading times in heavy games played from the slow UMD disc by copying some game files to the memory stick.

It is totally optional, and Peace Walker has 2 package install options: small package (320MB) and full package (880MB).

However, there is something special in how Peace Walker uses it: you must install at least the 320MB package to be able to have audio for CODEC calls during gameplay. If you decide to not install it, you will only get text in these calls.

The problem is, if you are already playing the game from a fast storage device in a real PSP/PS VITA (from an ISO/CSO in a CFW or even the PSN digital release) or in PPSSPP, this extra install is totally unnecessary and a waste of disk space.

Fortunately, I made a CW cheat to enable the audio in these in-game CODEC calls without having to install any of those packages, and the files will be read from the ISO/CSO itself.

Code:

Better late than never, right?
I have read in some forum that installing the 880MB package adds even more in-game audio for enemies or something like that, but I couldn't confirm this so for now this is all I can post. PM me if you have clear information about this and I will update the cheats.

Thanks a lot for that Right Analog Aim code, it's great to play Peace Walker with it
