Metroid Fusion on GameBoy Advance, comparison of CRT shader presets in RetroArch on PC

comparison of differeng slang shaders in retroarch with mgba core

other settings:

retro arch bilinear filtering off/video filter off/ audio filter: LowPassCPS.dsp (help decrease the courseness of the low sample gba audio)
I also set the scaling to interger and the ratio to 1.47 (its supposed to be 1.5 on gba, but circles look rounder for me at 1.47)

mgba core settings:
color correction: gba
Make sure to change the game to stereo at profile selection screen (select headphones instead of gba)
my preferred shader: RetroArch\shaders\shaders_slang\crt\crt-royale.slangp
