hopefully more mods possible on icr2 😀?
thank you

With this build no, it just has a fix for Scorched Planet. It's a pretty minor update, other than forcing 512 MB of RAM Dosbox-Staging-Rendition. Dosbox-Rendition already supported this. To allow ICR2 to run at full speed with 32 cars drawn ahead and 32 behind with custom carsets and tracks I *think* QEMU might be needed, which is what I'm trying to get going. This should allow the CPU side of Dosbox to run at full speed, using a virtual machine.

working configuration:

this is enabled in windows features:
Hyper-V Hypervisor enabled

this is disabled:
Hyper-V gui management tools
hyber-v module for windows powershell
hyper-v services
windows hypervisor platform

above is enough to have qemu working with whpx

but configure detects whpx with whatever setting i have (can be all whpx related disabled in windows features, but configure still detects whpx even if i have everything whpx related turned off in windows features)

so maybe turn on everything whpx related in windows features

maybe you have to install all packages with everything whpx related in windows features turned on

just uninstall msys2 completely, remove all leftover folders
turn on everything whpx related in windows features (reboot is always needed even if windows doesn't ask for it)
and install latest version again from here
https://www.msys2.org/
https://github.com/msys2/msys2-installer/rele … 64-20250221.exe

also check if qemu compiles with:
./configure --target-list=i386-softmmu --enable-sdl --disable-whpx --audio-drv-list=sdl,dsound

you install all packages in MSYS2 MSYS
but you do all qemu stuff in MSYS2 UCRT64

Edit: you do everything in MSYS2 UCRT64

I'll try again.

you have to run MSYS2 UCRT64 as admin

This produces an SDL2 error. But I did install sdl2. It does go a lot further.

[EDIT] Removing sdl from the sound options still produces the sdl2 error.

have you installed exactly all packages from here:

The uninstaller fails with an invalid path error. I'm just going to zap the folder.

have you installed to default folder?

this is not truth
you do everything in MSYS2 UCRT64

btw from your last picture i see you are running msys not ucrt64

Ok I had a full installation of MSYS2 left over from an earlier project, which is why the installer had issues. Also, the runtime libraries go in another folder. I've zapped both of those and reinstalled from scratch.

Previously I've tried building against a direct download of the last stable build of qemu and not rc4.

On this fresh install I followed your steps to the letter and got this:

1sharanga@ged MSYS ~/qemu-10.0.0-rc4
2$ ./configure --target-list=i386-softmmu --enable-sdl --enable-whpx --audio-drv-list=sdl,dsound
3Using './build' as the directory for build output
4
5ERROR: C compiler "cc" either does not exist or does not work.

[EDIT] I think I need to alias gcc as cc or create a symlink. I got a lot further with the previous messed up installation.

Yup you're right! My bad.

Does it need /UCRT64 or just vanilla UCRT?

I'll try it after lunch. Got some stuff to do.

all available shortcuts in

are:
MSYS2 CLANG64

After I reinstalled MSYS the shortcuts in that folder disappeared. I do still have them in the msys folder.

.exe is ok too
