So I installed Project64 (For those who don't know it is a Nintendo 64 emulation program so I can get my Mario fix), Which I always read is hard to put on a Linux. I didn't think I had WINE so I ran $ whereis wine and I guess I do. But I never set a config for it, So I don't get how an install through wine would work.

Question being - How was the .exe read?, Because I thought wine had to run to read those, and I don't think it ran. at least there was no visible sign when I installed.

I got my Project64.exe, put it in a directory I made, did the $ ch commands to change permission , did $cd <dir> then I ran ./Directory:$ Project.64.exe 'gamefile.z64' and it seems to work fine. except for it leaves the display as 800X600 after I close it.

Question being: Why is it changing display size, and not returning to my default-and can I make it stop doing it?

Try to run Wine in a virtual desktop mode, OR run the emulator.exe and change the video config from there (setting a resolution with a value that is the same as your desktop should work).

To change Wine settings run in a terminal:
