Key points

Although this fan-made port is available for free, it requires data from the Doom 64 ROM in order to work.
Great port that includes widescreen support, higher frame-rate, mouse look, and controller support.
Mouse aiming has been rendered broken on Windows 10 after the 2017 Fall Creators update. Use the SDL fix.

Issues fixed[edit]

Mouse aiming not working on Windows 10[edit]

After the Fall Creators update on Windows 10, mouse aiming has rendered broken without this fix.
Download the Win32 version of SDL version 1.2.15 and replace the outdated SDL .dll files in <path-to-game> with ones from the zip archive[7][8]

  2. In-game “linear” texture filtering uses 4-point bilinear filtering, rather than the 3-point bilinear filtering used on the Nintendo 64.[4] This results in more increased texture aliasing.[5]

  4. Doom 64 EX looks a lot better pixelated. - Doom General - Doomworld
    "I don't think the original filtering applied from the N64 matches the bilinear which the port uses, I feel the pc bilinear is making it look worse than the N64's own filtering."

    The blurring is quite noticeable. I have not noticed any issues yet caused by the LOD bias adjustment that Nvidia HSAA (and D3D Supersampling) force.

    Applying the SDL fix provided by dotfloat has addressed the mouse aiming issue under Windows 10 after the Fall Creator's update.
