RTC File format (reverse engineering)
Posted: Tue Oct 14, 2025 4:03 pm
So,
Looking at the one drive I see there's alot of RTC dungeons (namely the EOB one) which has the txt file with it but not the graphics.
Poking about in the asm, I've made some progress in determing how the encryption methods are achieved. It's essentially a XOR Cipher stream (keystream XORd against plaintext).
Now, this does not mean I can extract anything... It means I can only see unencrypted binary data (for now).
it's only a personal project, I find these kind of things to be some what of a puzzle, but if anyone's interested I can put it on github..
