The key checkpoint: Reproduce the specific recorded rendering change, then compare the same scene. Keep a game-image problem separate from a Windows blue-screen crash.

Before you start

• Use the recorded Eglantine build context.
• Change the demonstrated option rather than unrelated settings.
• Keep the original configuration so you can compare or revert.

The recorded rendering change

With Eglantine closed, open %APPDATA%\eden and edit nx2_switches.txt. Preserve existing entries and add EDEN_NX2_TENSOR=1 on its own line. Save with a single .txt extension, then fully restart Eglantine. The recorded baseline also uses Vulkan, Accurate CPU accuracy and Accurate GPU mode. These settings worked together in build 204; the recording does not isolate the effect of each change.

Walkthrough 01

Blue screen symptom

Video reference 0:00 ↗

If Donkey Kong Bananza loads but the world turns into this flat blue or purple screen, follow these settings and the text file change. This is the sequence that got the scene rendering in my recording. Close the game.

Walkthrough 02

System and CPU

Video reference 0:14 ↗

In Eglantine, open Emulation, then Configure. Under System, use eight gigabytes for Memory Layout, Normal CPU clocks and Boost GPU clocks. Keep the speed limit at one hundred percent. In CPU, set Accuracy to Accurate. In Graphics, select Vulkan and your graphics card.

Walkthrough 03

Vulkan and Accurate GPU

Video reference 0:31 ↗

Start at one times resolution. Open Advanced and change GPU Mode from Fast to Accurate. Then go to Extras and enable asynchronous presentation and asynchronous shader compilation. Click OK and close Eglantine completely. In File Explorer, open the address shown on screen: percent app data percent, backslash eden.

Walkthrough 04

Find nx2_switches.txt

Video reference 0:53 ↗

Open nx two underscore switches dot t x t. If it doesn't exist, create a text file with that exact name. Keep any other settings already in the file. Copy the line from the description and paste it into the switches file, exactly as shown.

Walkthrough 05

Add the tensor line

Video reference 1:09 ↗

Save it. Check the filename shown here and make sure Windows hasn't added dot t x t twice. Reopen Eglantine.

1:12 in the video · Add the tensor line. Select the screenshot to open this point in the original video.

Walkthrough 06

Restart Eglantine

Video reference 1:22 ↗

Choose File, then Load File, and select the same main file from your prepared game's exefs folder. Let the game finish loading. The restart makes the application read the setting you just saved. After these changes, the opening scene renders and the game reaches the mining tunnel.

1:28 in the video · Restart Eglantine. Select the screenshot to open this point in the original video.

Walkthrough 07

Confirm the fix

Video reference 1:45 ↗

Check the scenery and try moving and punching before adjusting more options. This was tested on build two hundred and four. If your screen still differs, compare the build, Accurate GPU mode, file location and exact tensor line. For the full setup, use the guide linked in the resources section.

If your result differs

Situation	Next useful check
The symptom differs	A Windows stop code is a different problem from the blue game image in this recording.
The workaround does not help	Record your game, build, GPU driver and exact scene.
A newer release changed the menu	Consult its notes; the old setting location may not apply.

Original setup notes and credits

Fix the blue or purple game screen in Donkey Kong Bananza on PC. Follow the Eglantine settings and nx2_switches.txt change used in this recorded test. Recorded with Eglantine build 204 and an RTX 4070 SUPER. This guide starts with your own prepared game files and an existing emulator profile. For first-run requirements, see the project handbook. This is an in-game rendering issue, not a Windows blue-screen crash. The settings shown worked together in this test; results can vary with the build and hardware. CHAPTERS RECORDED FIX System: 8 GB DRAM, CPU clocks Normal, GPU clocks Boost, speed limit 100%. CPU Accuracy: Accurate. Graphics: Vulkan, select your graphics card, 1x resolution. Advanced: GPU Mode Accurate. Extras: asynchronous presentation and asynchronous shader compilation enabled. Open %APPDATA%\eden and edit nx2_switches.txt. Preserve existing entries and add this exact line: EDEN_NX2_TENSOR=1 Save the file, close Eglantine completely and reopen it. Make sure the filename ends in .txt once.
