Hi I have a house of the dead ex that was 100% working but Japanese language. I bought a service keychip and i was able to change the region in the test menu hoping this would change the game to English. I put the original keychip back in but unfortunately i must have done something wrong because now it says "validate destination disk" then "setup for source disk" then "error 22 game program not found on device". I have no idea what the first two messages mean or why the game program is not found. What would i have to do to get this working again? thanks, any help would be appreciated.
