In Jaleco’s ‘Big Run’ (FBNeo core) there is no option to map ‘accelerate’ to a button. All other control functions are already assigned and can be remapped (brake, gear, horn etc). Only ‘accelerate’ seems to be missing.
I’ve noticed this bug on other racing/driving games (names which I cannot recall now) but Sega’s scaler racing games seem to work fine.
Is this an issue with the FBNeo core or with the RetroArch mapping? Can this be resolved?
