I made an automatic version of thdat (.dat compressor/decompressor). This makes the process way easier.
Works only with english patched games. I'll make a version for the japanese .dat's later.
Let's call it... thdat-sigma for now.
Download:
http://www.mediafire.com/?97wfk4tsqfckcg4Archive contains 2 exe. THDAT-SIGMA E v3 is for the English versions, THDAT-SIGMA J v3 for Japanese versions.
Usage:
- Put a touhou .dat file and THDAT-SIGMA E or J v3.exe on the same folder and execute. (If the game is Imperishable Night, it works with th08.dat, since the patch for this game works differently)
- Press X to extract.
- After the extraction is done, do all the alterations you want.
- Run THDAT-SIGMA E/J v3.exe again and press C to re-compress the dat.
Maav reported that after he tried to make an Invisible Bullet EoSD, the game bugged in some parts. I don't know what is the cause.
If you find any bugs, report them to me ASAP.
We will try to make tools like this for thmsg and thanm as well.
