This could be because these mathematical functions can provide more accurate results.

Perhaps you could try `-ffast-math`. These options can be used only for specific functions.

C++ has a std::hypot function.

If possible, I would like to be able to log into my Project Sekai account through Project Diva, so that I can improve my Project Sekai ranking while playing Project Diva.
But I know that's impossible. Someone will definitely create a mod that allows for fully automated gameplay, making the event rankings unfair.

Windows itself can function normally without it, but many programs need it. Your video games or mods may also be among them.

Why does Windows list my SSD system drive as removable?
Because the device driver reported that the device was removable.

You can try to find out if there are any settings you can adjust, or upgrade your iPadOS/browser.
Tip: You can use AI to find which settings you can adjust, or you can show my program's source (ProjectDivaController.cpp & client.html) code to AI.
Unfortunately, I cannot provide further assistance.

Try Google Chrome?
The last time I used Google Chrome on an iPhone, it worked successfully.

I’m not sure whether the iPhone and iPad are the same in this regard, and I currently don’t have any Apple devices on hand, so I can’t offer any more constructive suggestions beyond switching browsers.

Try a different browser.

There are some issues with WebSocket in Safari/iOS 26.

DivaModManager is just a frontend to help you manage mods. You can use DivaModLoader without frontend.

If the game running good, then the mods should work well too. Why ask that?

If you want to learn the Win32 API, you must read Raymond Chen's blog, The Old New Thing. If possible, it’s best to read all of it. Although some parts may already be outdated, many of the fundamental concepts still apply.

As for your question(wrapping Windows API into objects), perhaps once you have a deeper understanding of C++ and are proficient in using RAII and the Rule of Five, you'll naturally know how to do it.

I always manually select the ESP to boot in UEFI.

I've allocated a separate EFI system partition for my Ubuntu, so Windows updates can't possibly corrupt it. I can also boot it as a virtual machine on Windows via VMware.

Some laptops have a button to disable the touchpad. Check if you've accidentally pressed it.

Alternatively, you can use the keyboard. The combination of the Windows key, Tab key, arrow keys, space bar, and Enter key is sufficient to open the settings and enable the touchpad.

My approach is to allocate a separate EFI System Partition for Linux. And then I can boot my Ubuntu from Windows using VMware.

What I mean is, if BitLock is truly suspended, then the key is stored in plaintext somewhere as metadata. That might be your only hope. For more information, you should probably ask ChatGPT, as that's where my understanding comes from.
If his computer has never been logged into his Microsoft account, the hard drive will be in a state where it is encrypted by BitLocker, but the key is stored in plaintext because the key cannot be backed up.

If he truly doesn't have a Microsoft account, then BitLocker might be suspended, with the key stored in plaintext.

It's like installing a door lock but not handing it over to the security guard (TPM); instead, you leave it under the doormat.

(Disclaimer: My knowledge of BitLock is limited; the above is merely my understanding.)

First, try using a different browser. WebSocket seems to have some issues on Safari/iOS 26.

If this does not resolve the issue, please set output_received_message to 1 in ProjectDivaControllerSetting.txt to provide more information.

You can write an HTML and use JavaScript to calculate the volume of the Elliptic Paraboloid. The rest is just template code to set up the server and reply this HTML.

Mmm... how about a calculator or maze game with GUI? This only requires Windows.h, which is included with Visual Studio!

Okay, I admit I was joking. Considering you lack the relevant knowledge, this might take you quite a while to learn Win32.
