Stardew Valley on emuelec?

Hello, I have recently had undusted my old le potato emulator which I used for mostly playing snes games. But I had a craving stardew valley, I already owned it in steam and l’d figure I could get it running on Emulec. So l followed the steps of this tutorial:

I downloaded the Linux build thru steam. Pasted the files inside of the attached google file’s gamedata. Then I copied over the stardew valley folder along with the squashfs file to rom/ports and the .sh file to rom ports_script.

The game doesn’t boot when launched. Am I doing something wrong? Is my hardware too limiting?
