The duplicated button detection on the remapping menu is done entirely on the game's C++ code (Lua cannot have any involvements) so probably no.Do you think its possible to add controller scheme B from the xbox 360 version of SR2? Its impossible to recreate it with pc's controller remapping menu. (it puts accelerate and reverse on the triggers, but if you try to replicate this on pc it will always overlap with the left and right hand attack buttons)
I've found "control_scheme_text.xtbl" leftover in the game's files (download available below), but I'm unsure if it is actually used by the game.
It sounds like the Vehicle Surfing timer is accidentally enabled during the Mutiplayer matches.When playing multi-player (not co-op) there is a permanent timer affixed to the crosshair counting upwards from when a game starts to when it ends. Is this a glitch?
I cannot test anything MP-related beyond the pre-match lobby, but I've created a modified hud.lua that disables Surfing Timer during MP (download available below). Hopefully it works.
