I worked on the Metal Gear Solid port from PSX to PC, and Konami programmers chose a wild trick to store how the "C4" bomb was planted - either on the wall, or on the ground.
Essentially the pointer pointed to the same physical memory address, but if it was planted on the wall (or on the ground, I forgot) - then it was OR-ing it with 80000000h or was A0000000h - or maybe something else - lol was long time ago.
It was fun porting this on PC, and right now I don't even remember what I did exactly - hahaha
