Black screen on Dai Gyakuten Saiban english patch - hardware shaders unchecked

Issue:
Enter a description of your issue here, in full detail.
Hi all, I’ve been trying to run an English-patched version of Dai Gyakuten Saiban. Sound plays but no video - just a black screen. I tried the trick for turning hardware shaders off and still no luck. I am using Citra Canary 1370 - what can I do to fix this?

Here’s some issues I found with your log that might help.

  • Enabling Accurate Multiplication is recomended in certain games. If you are experiencing graphical glitches, try enabling this option.

Your GPU driver is outdated, download the latest from AMD’s website. also ROM modifications aren’t supported, if the issue persists try running your ROM without any modifications.

Hi there, I tried updating the GPU as suggested and also running the original (unpatched) file. I am still having the same issue. Do you have any other suggestions I could try?

Run your game again and reproduce the issue (black screen), close citra and upload your new log.

I don’t know why it still says 3.3.1, as I updated it.

according to your log your GPU driver is still outdated, you need to download your driver from AMD’s website, don’t use update utilities.
