How to get Sonic Mania to run at 1280×800 resolution?

[htv04]

I really Sonic Mania, and I play it a lot on my main PC. However, when I ran the game on my Linx Vision and set the game to full screen, the resolution was at 1080p, which meant that black bars appeared on the bottom and the top of my screen. Is there any way to get the game to run at my tablet's native resolution? Thanks!

Also if you want to know how I'm in the US and have a Linx Vision I imported it lel

It's a really good tablet to play games on.

Follow the instructions in the description at https://www.youtube.com/watch?v=TTguAwgm-5s except instead of selecting 4:3 select 16:10.

That seems to require hex editing the main game executable. Is there any way to set the resolution to 16:10 with a method other than hex editing? If not, what’s the value I should set the hex entry to?

In the Sonic Mania directory, there should be a file called Settings. Open it using a text editor, and in the section named "Video", place the words "pixwidth=1" on a new line, and then change the screen resolution options to 1280 for width, and 800 for height.

Can anyone confirm if this method works? I just want to make sure it’ll work before I edit the settings. Also, will the option work in full screen?

It should work, and I'll try it now. I can confirm that it works, as I have just tried it. The "main menu" looks a little bit glitched, but everything else is fine. If you change to 2x or 1x options for window size, it will keep the aspect ratio.

It works in fullscreen too? And does/could it crash the game at all? Sorry if I seem paranoid, I just don't want to mess up my game.

I just tried your method out, and it worked! I can see how some UI elements weren't meant for my 16:10 resolution, but it still works fine! Thanks for your help!
