Hey there. I downloaded the fbn's source (commit 'c2493a7'), added some romsets (in post90, neogeo and cps1-2), and compiled (vs2017).
I had some problems:
1. The mk Roms (I tested only mk, mk2, mk3, umk3) didn't work, appers only a black screen. Their emulation is private, and will only be available on github after the release of version *44?
2. Power Instinct (Brazil) did not work, only the warning appears: "There was a problem starting 'Power Instinct (Brasil)' "*
*code attached.
Ps: sorry bad english
