I've noticed a strange bug with FBN on Retroarch. When I load legend of hero Tonma (jap version, lohtj.zip), I got the World version ??
The rom is correct because when I load the same lohtj.zip with mame core (current), I got the japan version, so I think FBN is reponsible ?
Another question, why there are no warning japan copyright text at start for Irem M72 roms ? (R-Type is the only exception)
