The Ocarina of Time 3DS Rom Citra US: Fixing Uniform Block Size Issues

The Ocarina of Time is an iconic game in the Zelda series, and its recent release on the Nintendo 3DS has brought back memories of our childhood adventures. However, some users have been experiencing issues with the shader compilation and uniform block size, which can cause the game to crash.

In this article, we will explore the reasons behind these issues and provide solutions to fix them. We will also discuss the importance of querying uniform blocks correctly and how it can improve code quality.

The first issue that needs to be addressed is the shader compilation problem. The shader is even compiled because the compiler is not checking if the index is valid before querying the uniform block. This leads to incorrect results and crashes the game.

To fix this issue, we need to query the active uniform block with an index that is not equal to -1. In line 1338 of the code, we can see that querying the shader_data variable fails and returns -1 (4294967295). This is because the index is invalid, and we need to check if it is valid before querying the uniform block.

Another issue that has been reported is the uniform block size not matching. In the debug video_core/renderer_opengl/gl_rasterizer.cpp file, line 1084, an assertion failed because the uniform block size did not match the expected value of 960. This means that we need to check if the uniform block size matches the expected value before using it.

To fix this issue, we can query the active uniform block with the correct index and then check if its size matches the expected value. If it does not match, we can adjust the size accordingly.

In addition to these issues, some users have reported that their game crashes when playing on a Mac with the Nightly Build version 55c91ae. This could be due to an issue with the user's hardware or a bug in the build.

To fix this issue, we need to perform a fresh install of both Bleeding Edge-204 and the most recent Nightly build (1bf449d). We also need to use a blank user folder in the installation directory and not use the system_font or system_archives (Nand folder).

In conclusion, fixing uniform block size issues in The Ocarina of Time 3DS Rom Citra US requires careful querying of uniform blocks and checking if their index is valid. Additionally, we need to check if the uniform block size matches the expected value before using it. By following these steps, we can improve code quality and fix the issues that have been reported.
