- Ok guys.. Here it is.. A full crack for the install of Strike Commander..
- I've been waiting (like you guys) for this game for a LOOOONG time, and was
- sure that the UNT release was a Beta because of the "bugs" in the sim..
- I. E. "You've gone over to the Dark Side son!", and A being Eject..
-
- If these are happening to you, then you have a bad crack.. After thinking
- that it might NOT be a beta, I went in to see what Wayward did to crack it,
- and found the doc check routine, and it was a weird puppy. If you looked at
- each line, and determined what it did in your head, you would figure out that
- it was just an ordinary C input and ToUpper routine. They get the password,
- and convert it to uppercase, and then call an INT 15 with ES:DI pointing to
- the password you just entered.. I'm not sure exactly what that INT 15 does,
- I didn't get into it that far yet, but I did manage to find where they make
- the "fix" to let the game work. It seems that they take your password, and
- use it to generate a Dword value. They take that value and put it in the
- SC.EXE file. The game then looks at that value to determine if you get to
- play for real or not. I've installed this thing about 10 times this morning
- so that I could get all kinds of different passwords, and did them wrong, and
- strange.. They all generate the SAME Dword value if you put in the right one.
- Sooo... I make the program get the right value instead of the Computed value.
- (See code sample).. It always puts in the right Dword, and the game always
- works. Nice game, but not what the hype made it out to be. Just another
- F-16 simulator..
-
- Actual code from the routine to determine if you Live or if you Die..
-
- NOP ; Thanks Guys! I really needed this
- NOP ; Space to put my bytes to crack it!
- MOV EAX,[BP+06] ; Get the Dword from Storage
- MOV Dword Ptr [225F],EAX ; Put it in the buffer about to be
- ; Written to Offset $200 of Sc.exe
-
- This game was written to be cracked.. They left me a couple of NOP's in the
- right place so that I could put in the 6 byte op code in place of the 4 byte
- one that was in there.. THANKS GUYS! My theory is that the "In-House"
- version of this game had the same code in this place that mine does now, and
- they just changed a couple of bytes to make the "Production" version.
-
- Also, in case you didn't notice (I didn't until I got into the install), the
- SC.EXE is ALMOST the same file as INSTALL.EXE. They Copy Install.EXE over
- to SC.EXE, and then make the changes to it.
-
- The "Cinema" sections of the game are quite nice. I'm still waiting for
- someone to sync up the lips with the words being said. That'll be something.
- Now for my bitches.. FUCK the map generation! Put the maps on the disk! I
- HATE having to wait 10 minutes for it to generate the stinking maps! Also, I
- want to be able to pick ANY weapon for ANY mission. On Mission 2, I want
- MAVERICKS!
-
- Someone said that there is another doc check in the game somewhere.. If there
- is, get me a save game right before it happens, and tell me what to do, and
- I'll give it a shot..
