Secrets
Below is a list of unknown (“secret”) technical details:
- How to decode the
SP
chunk (that seems to be used to emulate EGA graphics in the VGA-version of the game)? - How did the original interpreter emulate CGA from EGA version?
- The
SL
chunk is always empty (and seems to be unused) – what was it meant for? - The frequency in the
CC
(Color Cycling) chunk is a mystery. It is big endian encoded. A value of 0xAAA is ignored. To calculate the delay, 16,384 has to be divided by the frequency. What is the delay unit - jiffies?
… Let me know when you know! 👀
