I had the idea to go ahead and make all the parameter files I have into params and slangp where possible, to clean everything up.
#reference "../../../../../../../shaders_slang/bezel/Mega_Bezel/Presets/Base_CRT_Presets/MBZ__3__STD__GDV.slangp"
#reference "../../../../../Params/Custom/Console Arcade/4x3.params"
HSM_BG_SATURATION = "0.000000"
HSM_BG_BRIGHTNESS = "10.000000"
HSM_BG_GAMMA = "0.450000"
HSM_DEVICE_HUE = "331.000000"
HSM_DEVICE_SATURATION = "88.000000"
HSM_DEVICE_BRIGHTNESS = "100.000000"
HSM_DEVICE_GAMMA = "0.450000"
HSM_CAB_GLASS_HUE = "331.000000"
HSM_CAB_GLASS_SATURATION = "88.000000"
HSM_CAB_GLASS_BRIGHTNESS = "100.000000"
HSM_CAB_GLASS_GAMMA = "0.450000"
IntroImage = "../../../../../Graphics/Custom/Console Arcade/Intro/MB.png"
DecalImage = "../../../../../Graphics/Custom/Console Arcade/Decals/MB.png"
Edit: I should clarify that I mean all parameter files, which includes OrionsAngel Realistic Arcade, lfan Overlays and Soqueroeu TV Backgrounds.
