x86 platform

[Sen15260]

Can we get an x86 versions of the game and of launcher itself? Tried to run the launcher on my Win10 tablet - obviously didnt work. Tried to install the appx downloaded by launcher - didnt work

[mojontwins]

Is it possible to compile the launcher for 32 bits? If so, how?

[mojontwins]

In fact, that was the easy part. I managed to compile for a 32 bits platform just by changing the target in VS. The app now works in 32 bit devices but the versions it downloads are still 64bits. I think the reason is this line in WUProtocol.cs:

new XElement(wuclient + "deviceAttributes", "E:BranchReadinessLevel=CBB&DchuNvidiaGrfxExists=1&ProcessorIdentifier=Intel64%20Family%206%20Model%2063%20Stepping%202&CurrentBranch=rs4_release&DataVer_RS5=1942&FlightRing=Retail&AttrDataVer=57&InstallLanguage=en-US&DchuAmdGrfxExists=1&OSUILocale=en-US&InstallationType=Client&FlightingBranchName=&Version_RS5=10&UpgEx_RS5=Green&GStatus_RS5=2&OSSkuId=48&App=WU&InstallDate=1529700913&ProcessorManufacturer=GenuineIntel&AppVer=10.0.17134.471&OSArchitecture=AMD64&UpdateManagementGroup=2&IsDeviceRetailDemo=0&HidOverGattReg=C%3A%5CWINDOWS%5CSystem32%5CDriverStore%5CFileRepository%5Chidbthle.inf_amd64_467f181075371c89%5CMicrosoft.Bluetooth.Profiles.HidOverGatt.dll&IsFlightingEnabled=0&DchuIntelGrfxExists=1&TelemetryLevel=1&DefaultUserRegion=244&DeferFeatureUpdatePeriodInDays=365&Bios=Unknown&WuClientVer=10.0.17134.471&PausedFeatureStatus=1&Steam=URL%3Asteam%20protocol&Free=8to16&OSVersion=10.0.17134.472&DeviceFamily=Windows.Desktop"))));

But I'm not sure what I should replace "Intel64" with. Any pointers?

[mojontwins]

I've checked the environment variables in system properties in the 32 bits machine, and I've got these results:

PROCESSOR INDENTIFIER: x86 Family 6 Model 142 Stepping 9, GenuineIntel
PROCESSOR ARCHITECTURE: x86

So hopefully changing that string so it reads...

new XElement(wuclient + "deviceAttributes", "E:BranchReadinessLevel=CBB&DchuNvidiaGrfxExists=1&ProcessorIdentifier=x86%20Family%206%20Model%20142%20Stepping%209&CurrentBranch=rs4_release&DataVer_RS5=1942&FlightRing=Retail&AttrDataVer=57&InstallLanguage=en-US&DchuAmdGrfxExists=1&OSUILocale=en-US&InstallationType=Client&FlightingBranchName=&Version_RS5=10&UpgEx_RS5=Green&GStatus_RS5=2&OSSkuId=48&App=WU&InstallDate=1529700913&ProcessorManufacturer=GenuineIntel&AppVer=10.0.17134.471&OSArchitecture=x86&UpdateManagementGroup=2&IsDeviceRetailDemo=0&HidOverGattReg=C%3A%5CWINDOWS%5CSystem32%5CDriverStore%5CFileRepository%5Chidbthle.inf_amd64_467f181075371c89%5CMicrosoft.Bluetooth.Profiles.HidOverGatt.dll&IsFlightingEnabled=0&DchuIntelGrfxExists=1&TelemetryLevel=1&DefaultUserRegion=244&DeferFeatureUpdatePeriodInDays=365&Bios=Unknown&WuClientVer=10.0.17134.471&PausedFeatureStatus=1&Steam=URL%3Asteam%20protocol&Free=8to16&OSVersion=10.0.17134.472&DeviceFamily=Windows.Desktop"))));

Will download 32 bits version? I'll try later this afternoon and keep you posted.

[mojontwins]

Nope, maybe that's not it. The launcher loads a list of versions from https://mrarm.io/r/w10-vdb, and such list contains hashes associated to only AMD64 versions.

For example, if you try to download "1.19.10.22", the list at https://mrarm.io/r/w10-vdb will use the hash 297a3833-310d-4bdc-9607-6443f7d28cb7 which, according to https://raw.githubusercontent.com/MCMrARM/mc-w10-versiondb/master/versions.txt, corresponds to the AMD64 version:

297a3833-310d-4bdc-9607-6443f7d28cb7 Microsoft.MinecraftWindowsBeta_1.19.1022.0_x64__8wekyb3d8bbwe 265544129

Fot the x86 version, this hash should be used (based upon the same list):

40a7b700-b554-468e-8a03-48cf04c847a2 Microsoft.MinecraftWindowsBeta_1.19.1022.0_x86__8wekyb3d8bbwe 265544130

I guess the file read by the app is pre-generated somehow based upon the general list. One possible solution would be pre-generate another file for the .x86 platform (and posibly another one for the .arm platform!) and point the 32 bits app to that, OR attempt to auto-detect the platform and download the proper version. But that's somehow beyond my posibilities, methinks.

[mojontwins]

I've created a very ugly php script which parses https://raw.githubusercontent.com/MCMrARM/mc-w10-versiondb/master/versions.txt for any of the three platforms (x64, x86, arm) and outputs a json array simmilar to https://mrarm.io/r/w10-vdb

https://gist.github.com/mojontwins/48c5eab5483a385f318dab1689f29c92

For instance, this is the output for the x86 platform:

https://gist.githubusercontent.com/mojontwins/8fed284f81a309d4355762c9ecc7b917/raw/738816cc8ba55daf70094cb15d284c38aebbb47e/gistfile1.txt

I'll try and create a MCLauncher which uses this list and see what happens.

[mojontwins]

Well, it worked - kinda. Now it downloads de x86 version but it's unable to launch it. Button stays on but nothing happens. Maybe I am not building the project correctly or there's a problem with my tablet. I'll try and generate a debug version later and try to understand what's failing.

My fork is here, BTW https://github.com/mojontwins/mc-w10-version-launcher

[DLazaridisGM]

can it download appx files at least i cant test it because i cant compile shit

[mojontwins]

It downloads, but fails to launch, silently. Maybe the windows version in this tablet is too old? I don't have another 32 bits system to test.

If, after downloading a 32 bits version in the tablet, I copy the whole folder to a pen drive and run in one of my 64bit boxes, I can play the game.

Here's a ZIP with the compiled x86 project which loads the x86 links and downloads x86 versions so you can test if you like:
MCLauncher.zip

Note that, in order for it to download a 32 bits version, it HAS to be run in a 32 bits environment, as the detection is made at runtime:

            if (Environment.Is64BitOperatingSystem)
            {
                api = VERSIONS_API_X64;
            }
            else
            {
                api = VERSIONS_API_X86;
            }

            {
                api = VERSIONS_API_X86;
            }

tested it just now on my win10 tablet (win10 21H1), works well and the game actually launches (unless i try 1.19 but that's due to increased requirements needed to run it)

[mojontwins]

Then it's time to update my tablet a bit. Thanks for testing!

[mojontwins]

Yay it worked! I'll tidy my stuff for a pull request

A very brief search of the issue tracker would have revealed that there are already several issues open about this: https://github.com/MCMrARM/mc-w10-version-launcher/issues?q=is%3Aissue+x86+

Hi @mojontwins. Can you make ARM32 version too? Need exact ARM32v7 compiled build because for MCBE UWP exist only ARM32 builds, and there is not ARM64v8 UWP builds. + ARM32v7 exe of launcher will support Jailbreaked Windows Phones and Windows ARM32 desktop build (it exist btw).

[mojontwins]

Sorry I don't have the means to do so.

ок. So sad
