libogc ucodes aren't implemented in DSPHLE
0%
Description
Game Name?
Project M Launcher (attached)
What's the problem? Describe what went wrong.
Freezes upon playing game. Doesn't occur with DSP LLE.
What steps will reproduce the problem?
- Launch Project M Launcher with DSP HLE
- Press "Play"
- Observe freeze. See attached log. Probably has something to do with the "Unknown mail sent to AX::HandleMail"
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
Project M Launcher can be used to load most Gecko OS compatible Brawl mods too.
For Android Gecko OS can run Brawl mods at about 11 FPS due to needing the cached interpreter (see #10786).
Project M Launcher + LLE gets the FPS in the upper 30's!

Could we remove the low priority status? A lot of people use the Project M Launcher for loading codes, Android doesn't have code editing in the UI, and Gecko OS has even worse problems.

It's been a known issue since 2015 and this is the first feature request about it AFAIK. Based on that, I'd say this is low priority, at least for the developers.

- Priority changed from Low to Normal
Now that I'm a developer who's interested in getting this implemented I can make it not low priority! No idea if this is difficult though.
Can someone tell me where ucodes can be found in Dolphin and then I can read up on them? If someone also knows where to find the ucodes to implement within libogc that will be helpful too.

From IRC:
A new ucode of CRC 0xa81582e2 needs to be implemented.
Dolphin handles this at https://github.com/dolphin-emu/dolphin/tree/master/Source/Core/Core/HW/DSPHLE/UCodes
libogc handles this at https://github.com/devkitPro/libogc/tree/master/libaesnd/dspcode and https://github.com/devkitPro/libogc/tree/master/libasnd/dsp_mixer

I don't know when I'll get around to looking into this again but I dumped the relevant UCodes.
And the launcher's "config.xml" still calls unknown opcodes even with:
<useSoundEffects>false</useSoundEffects>
<useMusic>false</useMusic>

- Milestone set to Current
Since the likely related issues involve serious errors and unknown opcodes I think this should be part of the Current milestone. Feel free to remove that status if the opcodes are actually unrelated to libogc.

I marked this as Current because it may fix other Current issues. Shouldn't we attempt to implement the relevant opcodes in the related issues before removing the Current status? Also, does that mean I should assume all libogc codes work in DSPLLE if I'm using a NAND dump? I'll retest the issues to make sure they work with DSPLLE and not DSPHLE.

I don't know what a NAND dump would have to do with it, but if there is an issue with libogc ucodes when using DSP LLE, such as unimplemented opcodes, then that is a valid issue that has no relation to this issue. This issue is about HLE implementation of libogc ucodes only.
#17
Updated by ryanebola16 7 months ago
Oh I just realized that a real DSP ROM isn't part of the NAND dump. Ok this all makes sense now. I'll assume that the unknown opcodes I found in the related issues are likely the causes of those issues. And if any of the related issues occur with DSP LLE I'll unlink them from this issue. Sorry for the confusion.
