This game works with Experiemental in Steam. I tried the current version, 5.13-6 like others mentioned, and latest ProtonGE with different types of issues. Experiemental was the only reliable means at the current moment, on the new Steam Deck OLED.

Forcing Proton 5 will prevent Fatal Errors when playing an Away-game in NBA Season. The only downside is a white background in the selection menus.

stuck at 720p will not let you change to full 1280 x 800
can only play exhibition game all other courts trigger fatal error crash
Rating a 3/10 as you cant play it now but probably will be fixed soon
Sadly no, exhibition on the default court works well, but other courts cause a crash with a fatal error...
I have opened an issue here https://github.com/ValveSoftware/Proton/issues/6558
Works perfectly fine with the Steam Deck controls or with an external controller. But I've found that after connecting and disconnecting an external controller (specifically, I've tried the 8BitDo Pro 2 bluetooth controller), opening and exiting the game each time, the next time it starts with only the built-in controller, it doesn't detect it anymore.
Rebooting the Steam Deck makes it work again, and probably there are other ways to make it work again too that I haven't found yet.
Filed this updated report to reflect controller use after my earlier report and to confirm the game is still generally great on Deck, after playing through a full single player season and more.
I've only played one game so far, but as far as I can tell, it works just fine with Proton 5.13-6 selected. Using the default version as of this writing, or when selecting Proton Experimental, the game launches, but it won't launch an actual (basketball) game.

Works great OOTB, just needed launch command to fix menu audio and Proton 5-13.6 otherwise Steam Controller wasn't recognized.

Launch command seemed to fix menu audio out of sync

Too many crashes…
Sound goes crazy in some menus. It's OK during a match.
Very often crashes at the begining of a match.
No he podido iniciarlo con ninguna versión de proton

The Menu Background is Missing or just White

Words great aside from music stuttering in the menu's on occasion. Multiplayer worked great as well.
The music in the menus will get out of sync on occasion.
native ,dont know how work on MESA but on nvida work native all ,menu....,online i play lot with kido ,gamepads works


The game itself runs perfectly. I'm using 4k resolution and its all working nicely without any tweaks.
But the menu background is missing something. Its just white.



Sounds in Menu are crackling (xaudio2_7 didnt effect), Ingame sound works normally.. the menu also missing background - its just white. gameplay is gold or even platinium


Just add x_audio 2_7 to Native/Bulletin in Winecfg and it works perfectly.
