This mod allows you to quickly toggle all HUD elements on/off with a single key press (Caps Lock by default, but this can be changed). You can also use F1 and F2 to toggle parts of the view you get while playing as Buddy (the Cagnali robot). See the screenshots for examples. I know Mal0 already has a mod for disabling the red filter over Buddy's view, but it doesn't let you hide the other bits like the scrolling text, and since that's a pak mod you can't toggle it mid-game if you wanted to.
INSTALLATION:
Extract the contents of my Toggle HUD for Crime Boss.zip to this folder (or the EGS equivalent): steamapps\common\CrimeBossRockayCity\CrimeBoss\Binaries\Win64
Boot up the game and use Caps Lock to toggle the HUD on/off, F1 to toggle minimal Buddy view, and F2 to toggle even more of Buddy's view.
TO CHANGE KEYBINDS:
While in-game press the Home key to bring up the ReShade UI, go to the "Add-ons" tab, and select "Edit" under ShaderToggler to pick a new hotkey. Click "OK", then "OK" again, then finally "Save all Toggle Groups".
