PPSSPP Feature Request Page

[Gurlok]

@Gurlok - Updates we download from psn are compressed and encrypted with update keys which we simply don't have and that might actually be the only problem as it updates "successfully" but with incorrect data hence breaking the game. Cannot imagine any emulator-side workaround for that.
Similar problem touches MHp3rd(the non HD version) or the extra dlc files that come with each GE2 update, we just don't have the keys to decrypt some things, that's where the real psp has to be used.

I see, that's a shame. My PSP is getting old enough, her battery is literally dying, so I was thinking about a solution to avoid the use of a real psp in order to update our dumps, thanks for clarifing this to me though .
