Decoding tsc files--How?

Does anyone know how to decode the numerous .tsc files into a semi-readable format? I'm refering to the actual process of decoding, not just how to read the files in Sue's Workshop.

Thanks in advance.

 

Use Miza...

 

Is Miza open source? I'm looking for the actual algorithm used to decode the scripts, if there is one. Also, I can't seem to find Miza via Google anyhow...

EDIT: Found Miza, but it doesn't work under Linux. From the look of it, it wasn't what I was searching for anyway.
EDIT: Aha! Miza help files pointed me to Dwedit, I typed in his name in Google with "Cave Story", and viola~. I think I found it. Thank you!

 

No prob

 

If I remember to check tonight, I'll have a look at my notes. TSC are... script, IIRC? They're encrypted using a weird-ass algorithm, but nothing too complicated.

 

The byte at (file length)/2 (rounded down) is the key to the file.

decrease all other bytes by that value (using modular arithmetic such that 0 -1 = 255), and you get the script in text.
