2. Hacking details
______________________________________________________________________
It took me about half an hour to find the code that handles palettes
and fading.
Here is how to disable fading between different rooms:
-In the USA version: At offset 0x00000C32 write: 4E 71 4E 71 4E 71.
-In the Europe version the offset is 0x00000BFC.
This hack doesn't affect the fade-in/out when starting or restarting
the level.
Also, this hack has a small bug:
when you meet the first guard, he will fade in from black. :)
Some details:
This hack actually disables the fade to black.
Due to the way fades are implemented, the following fade in will
take no time, since the displayed palette already matches the level
palette.
