config BR2_PACKAGE_MEDNAFEN bool "mednafen" help The mednafen game engine. https://mednafen.github.io/ if BR2_PACKAGE_MEDNAFEN config BR2_PACKAGE_MEDNAFEN_FAST bool "optimise for speed over accuracy" default y help Optimise for fast math functions, at the expense of accuracy. Say 'y' if you need speed and can live with inaccuracies in the results. Say 'n' (the default) if accuracy is of utmost importance. This basically uses gcc's -Ofast optimisation level, which in turn is basically using gcc's -ffast-math. See the gcc manual for what this means. endif
