I've made a fresh folder for MameUI64 and I want to open the main .ini file and mess about with HLSL and the integer scaling options, but I can't find the file anywhere. Is it supposed to automatically generate when I start MAME for the first time? What am I doing wrong?
Update- I've figured out how to make the ini appear after watching a YT video, but now I'm faced with another issue-
I'm trying to figure out how to make sure everything scales properly, both scanlines and the game screen itself. I'm playing a CPS1 1 game and the top & bottom parts of the screen are cropped out slightly and the scanlines are horribly uneven.

Can you post a screenshot and show us your HLSL settings, please?

Some time ago I described why it is not possible to have perfect even scanlines with a full-screen scaled image unless the vertical screen resolution is an exact multiple of the vertical native resolution of the game.
You can activate hlsl_oversampling to get a better interpolation between scanlines, but they will be still what you call "uneven".
If you want absolutely even scanlines, set the the unevenstretch option to 0 or run MAME with the command line option -nounevenstretch.
But I still don't see that the screen is cropped. The screen actually can be cropped if you already set the unevenstretch option to 0. The current MAME version can over-scan the image if the (auto) integer scaled image is slightly larger than the screen. You can prevent this by setting the integer scale factors intscalex/y manually.

Anyone who understands resolution and video display knows this, though.
