Button Mapping inconsistency Mame/Finalburn?

[rsn8887]

I noticed the buttons are assigned differently in Finalburn (libretro) and Mame (libretro).

I played Rainbow Islands. In Finalburn, B is jump and Y is shoot. In Mame B is shoot and Y is jump? Finalburn is the way it should be. Mame feels very awkward/wrong.

Is there any way to make these assignments consistent between the emulators?

I suspect it might just be some wrong button assignment in the Mame core...

@rsn8887 what is sure is that mame's buttons are B then Y, for any game. Which is pure stupidity

Yes I found this old issue on Github:

https://github.com/recalbox/recalbox-os/issues/914

It basically explains it: Mame buttons are inconsistently assigned and weird inside the mame drivers itself.

One would think that after decades of development, the Mame coders would have figured this stuff out and standardized it. But no...

At least is is correct in Finalburn.
