Emulator

Does this happen with both HLE and LLE, or only LLE?

ProjectM launcher doesn't work with HLE. There is a beautiful black screen right after we press play.

The only way to play ProjectM with HLE is to build a custom iso.

This looks like more icache issues with their new versions.

This basically means we can probably fix the bug with a 5-9x slowdown, or they can make their codes work on both Dolphin and Wii. We've noticed a lot of icache bugs in Project M recently.

So you mean the problem is the ProjectM code that have some issues, and for some raisons real hardware is able to handle them but Dolphin is confused?

use interpreter from startup; it'll be extremely slow. If it works in interpreter, then yes.

I did some testing with 4.0.2. Fun fact : 4.0.2 is fine with ProjectM even with HLE, it seems to be a regression :

I tried interpreter but it was too slow to determine if the correct music was played. I was too lazy to try again and dump audio.

That doesn't mean anything, unfortunately. When dealing with possible icache issues, it's very confusing as to what can affect what.

Ok. I'll try at least to find via revision bisection which revision caused HLE not being able to boot ProjectM anymore, and the one that breaks custom tracks.
Once I done that, I'll provide the sd.raw that contains ProjectM and the ProjectM launcher (dol) so it will be easier for the dev team to work around this issue if someone decide to handle it. Hope it'll help.

Once this is bisected, We can definitely take a look at it. Thanks.

Exactly which revisions are we talking about which broke/fixed the loader?

This is what broke the loader -> https://dolphin-emu.org/download/dev/0e0a196a1c3aefc3cd163de8d9e5636f4353a741/

I'm assuming it also broke the music thanks to the other issue report with the Rockband DLC not playing the right songs.

I'm fairly certain this is the commit that fixed the loader -> https://dolphin-emu.org/download/dev/f4e42b394c8a6d86463b2589f06598ae8bb217aa/

No need for the LLE tag since it's unrelated to DSP altogether.

Can run P:M Loader on HLE on latest Dolphin builds.

You just have to edit config.xml in virtual SD card (\projectm\launcher\config.xml) then set both SFX (useSoundEffects) and music (useMusic) to false.
