[GamePorter]

Hello!

Can anyone compile the emulator from source code + with a small code upgrade and post it here?

I create my build game Eternal Darkness: Sanity's Requiem for very slow PCs.
The assembly was based on the Dolphin 3.0-631 ICC XBHLE Patch emulator.
According to numerous trials, it was found that the game works "perfectly well" with the "Disable Lightning" hack option turned on, namely:

- At the beginning of the game, where the skeletons appear, the camera moves smoothly and without brakes;
- there is no dropdown of the FPS after the first shot in the same location;
- the overall performance is noticeably improved - the game works faster in difficult scenes.

The problem is the following:

- There are slowdowns of FPS when enemies accumulate on the screen in some locations (I tried all possible settings);
- while in the emulator versions somewhere after 4.0, there are no slowdowns when there are enemies, but it slows down in the cases described above due to the lack of the "Disable Lightning" option (it was removed after 3.0-691).

Found the source code of this option here:

I would very much like to see the "modified" emulator Dolphin 4.0 with the ability to select the "Disable Lightning" option in the settings.
It would have been a smart and productive build!

You can add this option, for example, in this Dolphin 4.0r607

Thanks a lot in advance. I will be very grateful!
P. S. Who will "help out" - those will be listed in the menu "Creators".

While a cut-down version of Dolphin for weak systems might sound good on paper, the reality isn't so simple. Thanks to modern hardware features, and removing old support that held back optimizations, Dolphin is faster than it has ever been! A modern Dolphin build paired even with budget hardware is going to run circles around a ten year old Dolphin build with high end hardware of that era. Having been with Dolphin in 2010, I know for a fact that that hardware wasn't good enough for Dolphin THEN, hence you needing to use a very bad hack (disable lighting) on top of an ancient build.

Also if you combine the hack with 4.0, you won't reach your performance goals anyway, since the 3.5-4.0 era of Dolphin was the slowest Dolphin ever was. Dolphin became tremendously quicker through the 4.0 era, through dropping old features that were holding back optimizations, said optimizations, and supporting modern hardware features. And if you tried to add that hack to a new Dolphin build, you'd basically have to redesign it from the ground up since Dolphin has changed SO much in that time!

So if you go through with this, you'll miss out on Dolphin's huge accuracy and performance improvements, so it would be slow, buggy, and unstable. I highly recommend you do a PC upgrade and just use a modern Dolphin build. Since you already have a PC to start from, even $300 for a budget motherboard, ram, and CPU would be sufficient to give you a HUGE improvement in performance! But until you upgrade, you should probably stick with that 3.0 era build and use the hack there, since it would be faster for you.

Aaaanyway, if this is something you still want to do, you'll really need to do all of this yourself. There isn't really going to be a lot of interest in making Dolphin worse to support ancient hardware. Plus, we don't support builds older than latest stable here, for all the above reasons.

Would it be easier to just disable it in the game code? I don't really know much about it.
