At firs, download lutris from store on desktop mode of steam deck.
Next you need download original game (you may use steam version) and NB installer (with new scripts).
In lutris app, you need configure folder path and wine prefix to same folder, where you keep your game folder. Also, you need to downlod exe runner in lutris. Use Proton experimental, or proton 8 or 7 ant choose it as a runner inside configuration of project.
Next, you need to configure winetrix. This settings you may find around Wine button. You need to download some distributive before install NB. You need choose: manipulation with prefix directory, and than download librates. You need dotnet (download latest), dsound and direct x (i cant remenber exactly, but just check discription or just look for tutorial at this forum "NB linux install" ), after that just wait for downloding (it doesnt showing the progress, so you need to wait before you take winetrix window) .
After that, you need to launch NB setup exe using wine prefix. You may find this option in the same way, that winetrix. When you start install, you MUST choose new render dx 11.
Wait for install.
If you cant start launcher, perhaps, you need to change compabiliti from win xp or 7 to 10. This option you may find in wine config, the same way that winetrix.
After instalation complete, go to wine config, choose "librates" and remove dsound from this list. After that, you may launch game.
