You guessed it right, I use Linux and I couldn't even use Wine when I needed to view some WAD files, Joe's editor was the only one I could use. It lacked an export feature however so I added that and redesined it to be reactive with Petite-Vue while at it The reason I had WAD files is not because of Half-Life lol, I just looked them up cause I wanted to view old-school textures and how they're made. I was interested in PSX style games cause it's a trend now and that was the first reference material that came to mind.
