Managed to compile using MSYS2 MINGW64 in admin mode:

instal dir for me is "C:\msys64\home\qwert\Nuked-sc55\build"

I had to crate the Nuked-sc55 folder inside the qwert directory, im guessing that is my username, so you will have something else there.

The sdl2.dll was not was not crated, had to get that from the pre-made build.

now, what is asio?

I couldn't figure out how to compile it, unfortunately.

The above code should give you all you need.

I used chatgpt for feedback on any errors. And it gave me code for it all to work.

might have to restart the compiler after installing the dependencies and then remove that line from code you give the compiler.

Can someone explain what ASIO support adds, or specifically if it adds something for emulation? Tried Googling it, didn't give me a clear answer. People here seem to be quite happy with it though, so was wondering if I'm missing out on something.

It's basically an ultra low latency audio protocol. For games you'll be just fine. If you were using Nuked-SC55 in place of a real MIDI module to create music with MIDI instruments. You might want it so the sounds play back more quickly. But for emulation you're unlikely to notice a difference.

Thanks!

New update from jcmoyer (https://github.com/jcmoyer/Nuked-SC55/releases):

Version 0.6.0 (2025-06-09)

This release contains bugfixes and a couple quality of life enhancements.

Enhancements

• Both frontends now default to locating roms by hashing files in the rom directory instead of requiring specific filenames. The old behavior can be enabled by passing --legacy-romset-detection to either program.
• Added more informative messages for loaded and missing roms.
• Added new command line parameters to override specific roms. These are meant for advanced users who have roms with unknown hashes. The parameters are: --override-rom1 <path>, --override-rom2 <path>, --override-smrom <path>, --override-waverom1 <path>, --override-waverom2 <path>, --override-waverom3 <path>, --override-waverom-card <path>, --override-waverom-exp <path>. Each parameter takes the rom filename to load.
• Added an --nvram <filename> parameter to both frontends. This is only used by the JV-880 and can be used to persist and reload JV-880 settings. (#36)
• Both frontends now send a GS reset by default when using a SC-55mk2 romset in order to work around a firmware bug that causes instrument pitch to be initialized incorrectly. Upstream defaults to not sending a reset, so this is a divergence in behavior. To get the old behavior, pass --reset none. (#38)
• Added the ability to route emulator audio to specific ASIO channels. (#39)

Bugfixes

• Fixed crash on startup when the directory containing the executable had non-English characters. (#30)
• Fixed renderer desync when using multiple instances and one of the instances received midi data starting later than tick 0. (#42)

Breaking changes for developers

• The emulator backend no longer depends on SDL. Emulator::Init now accepts an LCD backend pointer that can be used to customize the behavior of the LCD on a per-application basis. The old SDL backend has been moved to the standard frontend.
• Emulator::LoadRoms now requires rom data to be loaded into an instance of AllRomsetInfo by the caller. Several functions have been added to help with this. See emu.h for more information. A complete example can be found under common/rom_loader.h and its accompanying source file.

Let's decouple this fork discussion from main thread, i was so excited when this thread updated until i realized it was not updated after all 😅

I prefer it here.

Why? The forks are improving the main branch. Many of the changes are PRs to nukeykt's code base and might be merged to it.

Ah, didn't knew that, so be it!
