did a little trial of widescreen to try help a fellow who posted here and found the old bug is still present, and found this post regarding it on reddit from 2 years ago:

A somewhat recent revision in Dolphin (5.0-11841), while fixing some widescreen issues, has also unfortunately broken Dolphin's "Widescreen Hack" option for certain games; both Metroid Prime and Metroid Prime 2: Echoes has been affected by this bug. The last working revision was 5.0-11838 which can be acquired here. Direct link: https://dolphin-emu.org/download/dev/master/5.0-11838/

I can supply my save file if needed/wanted to test, as it is literally just before the final boss (not 100% on the energy packs and missiles, but close enough)

this is on the GM8E01 version of Metroid Prime for the Gamecube as a .ciso, using widescreen hack + force 16:9 + disable culling.

This is a known issue with dolphin's aspect ratio detection, as mentioned by Jos I believe. There's not much Primehack can do about this, though. This is a bug that needs to be fixed upstream.

Add

[Video_Settings]
SuggestedAspectRatio = 3

To your GameINI for any game with these issues to get around Dolphin's somewhat unreliable Heuristic Widescreen detection. Simply right click the game in your game list, Properties -> Editor -> User Config.

Generally the fix here is to force an aspect ratio and not rely on the broken heuristic as said above. Changing the ini files directly usually isn't necessary.
