    Ace Combat Assault Horizon Ace of Aces achievement + hex editting details

    Here is a save file for Ace Combat Assault Horizon. Play any Free Mission and when you complete it (it doesn't matter what difficulty or what score you get), you will get the Ace of Aces achievement (obtaining A ranking on all Free Missions). This was a super difficult achievement to get, only 128 people have it so far. I would recommend playing "Lock and Load" on Rookie difficulty, it's a on-rails mission and it's over in 10 minutes.

    I have also done 50hours of co-op/multiplayer and 50+ multiplayer kills, so these achievement *may* unlock as well, if you play multiplayer and get 1 kill. I don't know - if someone tries and report back, I would be grateful. Ace of Aces is the last achievement I got for this game, so if you haven't gotten all the campaign completion achievements, you should get those first, as my save file may unlock achievements out of order. The save file has bunch of skills unlocked already, and when you play a Free Mission, it will unlock a whole bunch of new skills as well as getting you the achievement.

    Now, I would like to discuss the save file hex structure that I discovered. If some one is interested in making an editor using my findings that would be great, as long as I get a mention :) If you are only interested in using the save file to unlock the achievement, you don't need to read the rest of this post. You may want to read the following to edit your own save file and not use my attached save file, and that would be fine as well.

    First, extract the save.dat from the savedata CON file. You don't need to, but it makes offset addresses easier, I think.
    Now search for 00 00 00 24 00 00 00 01 in save.dat. This should occur only once in the file, and for me it's at offset #0820
    Each Free Mission data has a size of 44 (2C) bytes.

    Grab 44 bytes starting with 00 00 00 01 (offset #0824 for me). It looks like this:
    00 00 00 01 00 00 00 04 00 00 00 03 00 00 07 6C 00 01 00 01 00 00 00 03 00 00 00 00 00 00 00 00 00 00 01 2C 00 00 01 7C 00 00 00 01

    I will divide this up and look at the individual components

    00 00 00 01
    is the mission ID/number
    (there is a mission in campaign called Shockwave, which is the 2nd mission, but is not part of Free Missions so 02 is skipped)
    04=Red Moon
    06=Blue on Blue
    07=Power Play
    08=Lock and Load
    0B=Hostile Fleet
    (0D is not used)
    (10 is not used)

    00 00 00 04
    is the number of times you have completed this mission

    00 00 00 03
    is the mission ranking

    00 00 07 6C
    is the mission score

    00 01
    ?maybe this is the aircraft ID that you completed the mission with

    00 01
    it's either 01 or 02, no idea what it is

    00 00 00 03
    highest difficulty you have completed the mission

    00 00 00 00
    00 00 00 00
    these are always 00

    00 00 01 2C
    cumulative machine gun bonus
    the following missions do not have machine guns, so are always 00 00 00 00
    Red Moon (04)
    Spooky (05)
    Lock and Load (08)
    Motherland (0E)
    when you get 200 or more machine gun bonus in every mission,
    you unlock "Gun Enthusiast" skill which increase MG damage and reduce overheat
    this number is cumulative. So if you play Blue on Blue twice,
    first time you get 50, 2nd time you get 70, this number will be 120 for this mission

    00 00 01 7C
    highest armor bonus scored
    when you get an armor bonus for every mission, you unlock
    "Untouchable" skill which increases firepower of all aircraft

    00 00 00 01
    mission type
    00=Gunship/Door Gunner
    01=Fighter or Fighter/Multi or Fighter/Multi/Attack
