I did it! I got the entire Nancy Drew series to work on Linux! Using Lutris, they all seem to work. At least, they boot up. I don't know if they'll actually be playable the whole way through, but usually, from my experience, if they boot, they run (except Trail of the Twister 😐 We'll see about her when we get there...).
After getting them all up and running on my 2011 MacBook Pro, I decided it was (probably) fine to wipe and install Zorin OS 17 on my 2017 MacBook Pro, and I'm glad I did. Not only do the games work just as good as they did on the previous machine, but the three problem games I was struggling with (Games 13-15), actually work! The choppy and laggy cursor is still there, and they all three still require dgvoodoo2 be enabled. However, the lagginess is SO much less noticeable on this machine. I'm assuming it's one of these things:
2011 MBP's have Gen 2 Intel Core i-series processors, meaning they do not have support for Vulckan. 2017 MBP's have Gen 7 Intel Core i-series processors. Therefore, they do.
2011 MBP's are thirteen years old, and, obviously, my 2017 machine is faster.
2011 MBP's have dual graphics, and on Mac's, specifically, graphics switching does not work. I do not know if my 2011 MBP is using it's Intel Integrated graphics or its AMD Radeon discrete graphics, or both, but there's a high likelyhood there's something buggy going on with those graphics in addition to the fact that they're both very old.
Either way, I'm absolutely thrilled to have all the Nancy Drew games working on Linux. The only downside is that Wine doesn't properly scale games on Wayland, so I have to use X11, for the time being. I'm so excited because Zorin OS looks absolutely gorgeous on Apple's Retina displays. There are a few Linux bugs that make this machine a little annoying to use, but, to be honest, the high resolution, better speakers, high display contrast, better performance, and better efficiency is so worth it.
