Hi,
FNA is a reimplementation of the Microsoft XNA Game Studio 4.0 Refresh libraries born by monogame.
it can run on win,mac,linux and same console, it supports x86/x64
https://fna-xna.github.io/
FNA is fully supported by Steam.
I converted the xna runtimes to make them work with fna, it is very easy.
I really hope you want to implement them officially
I attach an archive with fna runtime
and I link a fully working test project: https://www.eprime.it/download/spine_test_con_sprite.zip (sorry we work in vbnet 😉 )
as xna, olso fna has the Y inverted, please fix it :grinteeth:
regards
Cristian
