3. Detailed Steps to Repack a Game

Repacking a game involves several steps. This may not have great results and follow the steps closely.

3.1 Step 1: Adding the Game Folder to a FreeArc Archive with No Compression

The first step is to add the game folder to a FreeArc archive with no compression. This can be done using the following command:

freearc a -m0 archive.arc game_folder

This command creates an archive named archive.arc containing all the files and folders from the game_folder directory without applying any compression. The -m0 flag specifies that no compression should be used.

3.2 Step 2: Running the Archive Through Precomp

The next step is to run the archive through Precomp. This can be done using the following command:

precomp.exe archive.arc

Precomp optimizes executable files within the archive for better compression ratios by reordering and transforming the data.

3.3 Step 3: Running the Precomp Output Through Srep

After running Precomp, the output file should be processed with Srep. This can be done using the following command:

srep.exe archive.pcf

Srep finds and replaces repetitive sequences in the file, further improving compression.

3.4 Step 4: Running the Srep Output Through FreeArc with Maximum Compression

The final step is to run the Srep output through FreeArc one more time with maximum compression. This can be done using the following command:

freearc a -mx -ld800m final_archive.arc archive.srep

This command creates an archive named final_archive.arc containing the Srep output file, using maximum compression (-mx) and a large dictionary size (-ld800m).
