1 month ago I've just created the changes branch to assist with debugging, particularly in comparing the non-RTX and RTX versions. This branch includes two commits:
- The first commit contains all the modified files from the
render96ex-alphabranch, which is the non-RTX version. - The second commit includes all the changed files from the
render96ex-tester_rt64alphabranch, which contains the RTX-related changes, along with any new files.
By focusing only on the affected files in these commits, it should be easier to pinpoint the exact differences between the non-RTX and RTX versions, helping with the debugging process.

[Integration of RT64 Support into sm64coopdx]
Background and Context: This pull request focuses on integrating RT64, a raytracing rendering API, into the sm64coopdx project. The main branch of sm64coopdx does not currently support RT64, so this integration required significant modifications and careful merging of changes from specific branches and repositories.
To implement RT64, I created a branch named rt64_dynos within my sm64coopdx repository (https://github.com/iZePlayzYT/sm64coopdx). The main branch of my repository, which is also used in this PR, is identical in content and state to the rt64_dynos branch. Initially, a few days ago, I attempted to port the RT64-related code from the fsr branch of the sm64rt repo (https://github.com/DarioSamo/sm64rt). However, I decided to abandon that approach due to incompatibilities and instead started from scratch using the tester_rt64alpha branch of the Render96ex repo (https://github.com/Render96/Render96ex), which, like sm64coopdx, supports DynOS.
After extensive work, I successfully merged the RT64 changes from the
tester_rt64alphabranch intort64_dynos. This effort allowed the project to compile without errors. However, I encountered significant graphical issues during runtime.Graphical Issue and Debugging: When launching the game, a graphical error occurs, leading to an incomplete render where only the ImGui F1 menu is responsive. The rest of the game freezes, which indicates that the issue is related to the graphics rendering process. Through debugging, I discovered that two specific shader IDs, both starting with
0x490EB(as seen in the attached screenshot), are repeatedly attempted to be loaded by the functiongfx_rt64_render_thread_preload_shader. These attempts happen continuously after the last console output in the game, suggesting that these shaders are either missing or incorrectly referenced. Despite the successful compilation, the rendering process fails due to these issues, resulting in the graphical errors seen.Challenges and Unresolved Issues: In addition to the shader loading issue, there were two critical aspects that I couldn't successfully merge into my
rt64_dynosbranch from thetester_rt64alphabranch of Render96ex:Makefilein sm64coopdx lacks a basepack, which is essential for resource compilation. The absence of this basepack has caused confusion about how to proceed with the resource-building steps.load_textureMethod: The codebase lacks aload_texturemethod, which is typically used for handling textures in the rendering pipeline. This missing functionality is likely contributing to the observed graphical issues.These issues are specifically related to the recent work on the
rt64_dynosbranch, which is derived from the Render96extester_rt64alphabranch. Thert64_normalbranch, which was previously based on the sm64rtfsrbranch, is no longer relevant, as that approach was cancelled in favor of starting fresh withrt64_dynos.Request for Assistance: I am seeking help to resolve the graphical rendering issues, specifically related to the repeated attempts to load shaders with IDs starting with
0x490EB. Any guidance on properly implementing or bypassing these shaders would be highly appreciated. Additionally, advice on how to resolve the basepack andload_textureissues within the code would also be beneficial.I’ve also created a video that shows the compilation and startup process of this integration. The video demonstrates the successful compilation, the startup, and the current graphical issues. Watching it might provide more context and help with troubleshooting.
