The House of The Dead 2 - SEGA Naomi Widescreen Hack + Gun calibration Tutorial for Flycast

Go to cheats menu and then click on add cheat. There type/ paste these two codes like I've shown in the video:
029C2AD8
43700000
Make sure to tick the checkbox for the widescreen cheat to activate. Do not enable the widescreen hack from video settings in flycast, that causes pop in and objects despawning outside of the 4:3 area.
The gun calibration will be incorrect. It's hard to find out the exact spot to have the cursor aligned. But as you can see in the video, for 16:9 aspect ratio- it's kind of easy to find the exact spot thanks to the blinking arrow.
