To preface this, I am completely new to linux/PC gaming and have virtually no knowledge about any of this stuff, but I'm trying to learn, so any help or advice is appreciated. I just got my Steam Deck recently and was really looking forward to playing this demake. I even saw a video on twitter of someone successfully running it on their steam deck, but I've been having trouble over the last couple days getting it to run and am at the point where I need to reach out for help.
I went into desktop mode on my deck and was able to download and unzip the folder, and after some trouble was able to locate the BBPSX-Win64-Shipping.exe and add it as a non-steam game to my library. I then went into properties and set it to force the use of Proton Experimental, but I can't seem to get the game to launch, when I click play nothing happens.
Do I have to use Lutris or some other program (something called Wine? I'm not familiar with any of these) to get it to run properly? I installed Lutris the other night after failing to run the game via my Steam library, but I can't seem to find a way to add the .exe file to lutris—everytime I go to add the game from the folder on my desktop the .exe file will not show up in the search, even though I can see it right there when I open the folder on my desktop. I've also read that maybe some people need to run Lutris with certain prefixes like Wine64 (I don't even know what that means) in order to get it to run, but I don't know how to do any of that.
TLDR: I love Bloodborne, love the work put into this project and would love to play this on my deck, I'm just kinda dumb when it comes to linux/pc gaming. If anyone can help me get it up and running I'd appreciate it. Thank you!
