Screen resolution issue with ZSNES

I'm using ZSNES on my Ubuntu arcade cabinet with a vertically oriented monitor. If I run with just:

zsnes -r [romfilename], half the game is off the screen.

My screen resolution is 1280x1024, and if I set that as the custom screen resolution in ZSNES and run it with "zsnes -v 22 -m [romfilename]" it works, but the right edge of the screen is off the screen.

Any tips on getting zsnes to run on a vertical monitor?

Or maybe there's a different emulator that would work?

Try compile higan or bsnes.

https://higan.readthedocs.io/en/stable/install/linux/

https://github.com/higan-emu/higan

https://github.com/bsnes-emu/bsnes

I cant find guide to compile bsnes.

As debian user i can help you compile both.
