Thank you, without the contribution of everyone here none of this would have happened.
MD5 that pop fe presents to me:
SLPS-01853
MD5: 015f07b3e52befbb72db3ebd60657ffa (When translation applied to a REDUMP image.)
MD5: 86ab07971eb0729ff6d0401078d7ef6a (When translation applied to the image on which the translators were based at the time.)
And the original translation patch is here:

Below ppf for Skullmonkeys (USA) SLUS-00601, without this ppf the game will give a black screen on PSP/Vita.
Thank you very much
