If a game works on one OS, why not on another?

I’ve got two Lakka setups. One on x64 and one on Raspberry PI 2. I have a few FBA games that work fine on the Pi2 and not on x64. The Rom folders, system folders are exact replicas.

Shouldn’t a game work in one if it works in another? I’m assuming that once it is handed over to the FBA core, the rest should be in there, no?

Sorry - just trying to understand how all the pieces work together.

Hi asymptote.

What are the names of those games?

The code source is not strictly exactly the same on different architetures. There are some ifdef. Also, the compiler optimizations chosen vary a lot. So the resulting binary can be very different.

Specifically I remember frogger and dig dug but I think there are a few others.
