Prisoner of Ice: Jashin Kourin English translation
プリズナー・オブ・アイス ～邪神降臨～ · Call of Cthulhu: Prisoner of Ice
Plissken's patch that brings the English text and voices of the PC original into the Japanese PlayStation port of Prisoner of Ice.
What's translated
Since the game was first made in English for the PC, Plissken carried the original English text and voice acting over to the Japan-only PlayStation version instead of writing a new translation. He made a Russian version too, and a Saturn version of the patch followed shortly after.
Other languages
A Spanish conversion, based on the official Spanish release of the PC game, was made later with Delta Island, IlDucci and Cerbero.
Playing it
Apply the patch to your own copy of the Japanese disc, following the instructions from Plissken.
