How to overcome it?

CRC Checksum Error - Data\textdata_eng.lua and all textdata we can not change.

fixed thanks :)

Before asking for help, you should explain your intention first. Are you trying to bypass integrity as a whole or is it just the specific TEXTDATA_ENG.LUA check preventing you from changing data for a private server?

Try to find the function that exits the game and patch the message box and profit.
That's what I did a few years back.

Just patching a messagebox can not prevent the game from exiting after the messagebox did (not) show up.
What I did was just easy.. I patched the crc checker function (return). This prevents future crc checks from being performed (they check if crc check has been initialized. if so: check a file. if not: i dont care).

Another solution would be to patch your global.fcl to match your changed file. But this changes the checksum of your global.fcl. In this case, you can modify a 32bit block to match the checksum again. For this I use any deprecated entry in the global.fcl (most files are useless in this file however).

That's why you have to patch the exit function as well. Kinda obvious huh?

Or just put 0 to static address ;) and you don't have any detection...

What if I told you I wanted to exit the game...
There's only the taskmanager option then

Check for return address then? Duh!

The return address isn't better solution...with my method all check to edited files are bypassed...no .code section patched!

sorry to butt in, i would nee exactly this:

>the specific TEXTDATA_ENG.LUA check preventing you from changing data for a private >server?

how can i do that?

Is it just 1-5 files or will you constantly change things? It would make sense to disable the CRC completely then (memory-wise). If its just a few files, you can either patch each files global.fcl entry or patch the files themselves to match their old checksum eventhough they have been changed. PM me and Ill help you.
