Editing Widescreen hacks

A '''widescreen or ultrawide hack''' is an emulator enhancement feature that make older games playable on 16:9, 21:9 or 32:9 aspect ratios without stretching. (View Frustum)[https://dolphin-emu.org/blog/2024/02/10/dolphin-progress-report-november-and-december-2023-january-2024/#50-20785-support-custom-aspect-ratios-by-filoppi]

Most video games before mid-2000s were developed for TVs and monitors with 4:3 aspect ratio. If these games are played on 16:9 aspect ratio, the game is either displayed with black bars on each side or stretched to fill the whole screen. Some emulators however provide a widescreen hack option to make these games look nice on modern monitors.

Some games before mid-2000s do have built-in 16:9 aspect ratio support, but usefulness of this option will vary. Some games just add black bars to top and bottom, while others have very zoomed out camera, so widescreen hacks may still be useful in these games.

==Limitations==
A widescreen hack basically hacks camera size and position, so depending on the game there might be graphical glitches.
*2D sprites/HUDs such as health bars or minimaps might look stretched or displayed on wrong location.
*Enemies or objects outside of 4:3 area might suddenly appear or disappear, because the game skips rendering for offscreen things. Similarly, the screen-wide visual effects such as fade-in and fade-out may only affect the 4:3 area of the screen.
