Decompiling a game means reverse engineering the game to a point that you have a program written in C that compiles to identical machine code as the commercial release. That makes it easier, but not entirely straightforward, to just compile the game for another architecture, because it might be written for hardware-specific features that might not be present on, say, PC.
A minor example is Mario Kart 64 has these big screens around some tracks that are playing footage of the race. That relies on a hardware quirk peculiar to the N64 and it’s been difficult if not impossible to get it working anywhere but real hardware.
A really weird one is Super Mario 64. The retail version of the game was apparently compiled with debug flags on. The game has been decompiled, and then compiling it without the debug flag actually causes the game to run smoother, particularly in Dire Dire Docks which chugs so bad on a retail cartridge that speed runners use camera strategies to keep the submarine out of view for better performance.
In some ways yes.
