Sorry for necroing this thread, but did you find a solution for the Guadalcanal bug on the GOG version ? I encounter the same frustrating bug.
Download the MOHPA_1_1_to_1_2.exe patch via the Wayback Machine's cache of http://largedownloads.ea.com/pub/patches/MOH/Pacific_Assault/
, or via Mod DB
. Extract the contents of MOHPA_1_1_to_1_2.exe (I used Universal Extractor for this). Among the contents of the executable is a cabinet archive named data1.cab. Next, extract the contents of data1.cab (you can use Universal Extractor for this as well). Within the contents of that cabinet archive is a directory named "main", and inside that directory are two LithTech Rez archives. pak9.rez is the archive needed to fix the objectives issue. Copy pak9.rez and paste it in the following location:
If GOG Galaxy- Program Files (x86)\GOG Galaxy\Games\Medal of Honor - Pacific Assault\main
If GOG sans Galaxy- GOG Games\Medal of Honor - Pacific Assault\main
This will replace the game's existing pak9.rez, so you might want to back it up first. Also, you will need to complete the Guadalcanal hidden objectives again. If you are going to use an existing save as opposed to restarting the game from the beginning, then you will likely need to restart from your last Makin Atoll save (e.g. "Sitting Ducks - Nautilus Defense") as opposed to restarting from a Guadalcanal save.
PS Unrelated, but the Director's Edition content can be found at https://www.moddb.com/games/medal-of-honor-pacific-assault/downloads/medal-of-honor-pacific-assault-directors-edition
Hi. Thank you for posting this fix (and the link to it in a related thread). I´ve downloaded the patch and extracted it and then the data1.cab using Universal Extractor per your instructions. Now, there is no "main" directory directly. I did find it in the "English_Files" directory, but that one only contained pak10.rez. I found the "main" directory containg pak9.rez in a directory called "Patch_Files_Uninstallable". Not sure why the path is not the same as you described. Maybe because of the version of Universal Extractor I used? Anyways, I replaced the pak9.rez file as you describe (I noticed the file is also present in the same location in data2.cab ).
Now, thing is, I´ve had this ´uncompleted hidden objectives / missing medals´ bug in most of the missions. Not just Guadalcanal, but also Boot Camp, Makin, and Tarawa, despite definitely completing them. In Boot Camp for example, I was missing the objective of having 50% accuracy on the range (despite having the ones for 75 and 100). I decided to start a new campaign to snatch all the missing medals rather than just Guadalcanal, but after completing Boot Camp, I had the same bug again. Missing the objective for 50% accuracy.
So I´m wondering, are other people having this bug with other missions than Guadalcanal as well, and if so, is the solution to it hidden in a different file than pak9.rez, or have I done something wrong when replacing the file?
EDIT: So I decided to try one more thing and copied the pak9.rez file from the data2.cab archive´s directory instead, replayed Boot Camp, and this time all medals unlocked! I´ll continue the campaign over the next week and see if all the others do as well.
