How to actually unlock all DLC

CAPCOM pulled from the stores all the DLCs. However, because they're already downloaded in the game files, you can bring them back with just a simple code. It's morally correct to get them back.

I'm not gonna add dots to links so Steam doesn't detect as links and deletes them off.

0. Go to game folder ...\steamapps\common\Dead Rising 2 Off the Record and rename steam_api.dll to steam_api_o.dll
1. Open Google and search for the cs rin ru website. Register an account on it.
2. Search for the forum thread called [Release] CreamAPI - A Legit DLC Unlocker.
3. Download the latest release. As of writing this guide, it's Current Release v4.5.0.0 Hotfix.
4. Extract the .rar somewhere and open the files. inside ...CreamAPI\log_build are 3 files.
Copy steam_api.dll and cream_api.ini and paste to the game folder

5. Open the cream_api.ini you pasted in your game folder, and replace everything inside with the following:

[steam]
; Application ID (http://store.steampowered.com/app/%appid%/)
appid = 45770
; Current game language.
; Uncomment this option to turn it on.
; Default is "english".
;language = german
; Enable/disable automatic DLC unlock. Default option is set to "false".
; Keep in mind that this option  WON'T work properly if the "[dlc]" section is NOT empty
unlockall = false
; Original Valve's steam_api.dll.
; Default is "steam_api_o.dll".
orgapi = steam_api_o.dll
; Original Valve's steam_api64.dll.
; Default is "steam_api64_o.dll".
orgapi64 = steam_api64_o.dll
; Enable/disable extra protection bypasser.

extraprotection = false
; The game will think that you're offline (supported by some games).
; Default is "false".
forceoffline = false
; Some games are checking for the low violence presence.
; Default is "false".
;lowviolence = true
; Purchase timestamp for the DLC (http://www.onlineconversion.com/unix_time.htm).

;purchasetimestamp = 0

[steam_misc]
; Disables the internal SteamUser interface handler.

[dlc]
; DLC handling.
; Format: <dlc_id> = <dlc_description>
; e.g. : 247295 = Saints Row IV - GAT V Pack
; If the DLC is not specified in this section
; then it won't be unlocked
45775 = Dead Rising 2: Off the Record Cyborg Skills Pack
45773 = Dead Rising 2: Off the Record BBQ Chef Skills Pack
45774 = Dead Rising 2: Off the Record COSPLAY Skills Pack

Also the game bans are different on each game. I can't say what would happen exactly if you got banned on Dead by Daylight but suffice to say you won't play the game since it's an online only game

[DISSIDIA 012 [duodecim]]

Sorry for late response. It's more likely to get banned from the game itself than Steam. Steam is very lenient and will give you a "1 game ban on record" on your profile

[Aske]

"get you banned in the game or steam" you mean my steam acc will be gone or I won't be able to play the game I banned on steam?

[DISSIDIA 012 [duodecim]]

It is said that some games that have server side checks such as Dead by Daylight and COD will get you banned in the game or steam. Last I heard just don't try it with live service games...

[Aske]

can creamapi get u banned?

[DISSIDIA 012 [duodecim]]

Strange. Seems like you're having the issue many people said they had with the DLC originally when it was on the store. Can't help you with that, sorry. Maybe verifying game files but I suppose you already did that. I don't know

[We are Legion]

The game gives me an error message when I go into the locker that says "Downloadable content appears to be corrupted and cannot be loaded. Please try to download the content again."

[We are Legion]

I already tried that.
Same result.

[DISSIDIA 012 [duodecim]]

That's very weird. You should try the CreamInstaller thing that pops up in Google in the Github page. Maybe that'll work?

[We are Legion]

This only partially worked for me.
I can't access the BBQ Chef outfit.
I don't know why.
