Space EX Sergeant Decoder
What you need
DAW of choice (Pro Tools/Logic Pro etc.)
Computer (Tested with Windows XP 32 bit)
Step 1 - Downloading
Click the download button above and unzip the file provided.
Step 2 - Bouncing Audio In and Out
Put the unzipped folder aside for now, you'll need it in order to convert your audio back to files. Right now we want to bounce our audio off the tape into our DAW of choice. Make sure it's a clean, hot signal, almost to the point of peaking. Tip: Keeping everything mono is your best bet when recording the signal from tape to digital. When bouncing audio out of our DAW, the specifications are crucial and must be followed correctly, otherwise the decoding process will result in failure. It's important to name your WAV files something simple so there's no confusion wen decoding. We'll use the filename A01 for this example. Here are the audio output specifications:
Bit Rate: 176 kbps
Sample Size: 8 bit
Channels: 1 mono
Sample Rate: 22kHz
Audio Format: PCM
File name: A01
Step 3 - Preparing Your DOS Batch Files
With your new WAV file bounced out including the correct specifications, it's time to decode the data. Place your WAV file in the main folder KCS08 Master Sergeant. Right click on the file titled decode ignore errors.bat and choose Edit. This file can be edited in a normal text editor. You should see the following script:
KCS -Y -U FILENAME.wav FILENAME.bmp
We need to replace the words titled FILENAME to what we named our WAV file in Step 2. In this case it's A01. Save the file and exit the Text Editor.
KCS -Y -U A01.wav A01.bmp
NOTE: The last two tracks are .mod files and must be specified in the decode ignore errors.bat code.
KCS -Y -U A01.wav A01.mod
Step 4 - Decoding Your Audio
After your newly edited batch file is saved, you can now execute the command by double clicking on the file. You should see a command prompt pop up for a brief second. Don't touch it, just let it finish.
Step 5 - Viewing Your Files
If everything was done correctly, a new file will pop up in the main folders directory. In this case, we decoded the first Bitmap Image hidden on the B side of the Space EX Soundtrack! Remember, the last two track on the cassette are .mod files and should be specified within the Batch files output code.
Step 6 - Encode Your Own Files (Optional)
To encode your own files, simply right click on encode.bat (batch file) and choose edit. The FIRST FILENAME is your input file, while the SECOND FILENAME is your output file. Your input file can be anything from PNG, text documents, applications, videos, passwords, basically anything digital. In this example we'll look at encoding a text document. Note: Yellow is input, Red is output. Just replace FILENAME with your files. To decode, revert to Step 3.
KCS -M -Y -U -L5 FILENAME.bmp FILENAME.wav
KCS -M -Y -U -L5 document.txt document.wav
