Modern Minecraft 1.18+ On XP x64 Is It Even Possible?

[legacyfan]

ive recently been using windows xp x64 (my computer is one of the rare ones with official drivers) and was wondering if it would at all be possible to run minecraft 1.18+ on it or if this is just a bad idea? If anyone could help with this it would be much appreciated

Yes, you need OCAPI and OpenJDK 17 (Adoptium). I haven't actually tested it but it should just work since Java 17 works.

I thought one-core-api was considered illegal? (it used some stuff that was illegal meterial)

idk it still exists on Microsoft owned GitHub so

I did make a post about this on my forum, going to mirror it here.

It's not the easiest or the best method, but it's the one I like to use.

I use AdoptOpenJDK, and up to release 8u242 works. However you will need to mod it.

For XP x64: https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u242-b08/OpenJDK8U-jre_x64_windows_hotspot_8u242b08.msi

For XP x86: https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u242-b08/OpenJDK8U-jre_x86-32_windows_hotspot_8u242b08.msi

To modify it for XP, you'll need these two below.

Orca: https://www.technipages.com/downloads/OrcaMSI.zip

winvertroll: https://board.eclipse.cx/viewtopic.php?t=652

Install Orca, then right click the OpenJDK8 installer, and click Edit with Orca.
In Orca, go to Launch Condition, select the one with "Windows 7 or later is required" as the description, right click and drop row.
Save and close Orca, then install OpenJDK8.
Navigate to C:\Program Files\AdoptOpenJDK\jre-8.0.242.08-hotspot\bin, and drag both java.exe and javaw.exe onto winvertroll.exe.

Now you have Java 8 on XP!

For Java 17, you need One Core API. One Core API is unstable, but is the only way to get this working as far as I know.

Get Java 17 from here: https://adoptium.net/temurin/releases/

Select Windows as Operating System, and JRE as Package Type.
Download the one for your system.
Repeat the Orca steps for Java 17 and install.
If this fails, I've only tested with 17.0.5+8, which can be found in the archive. The latest should be fine, but I haven't tested it. I will soon though.

Now you have Java 17 on XP!

Does Java 17 will work on Vista with Extended Kernel?

Yes, you don't need to patch it with winvertroll, but you do need to edit the MSI with Orca iirc.

Here's an old screenshot I made for unrelated reasons. It shows 1.16.5, however it also shows Java 17 in the top right.

i forgot this thread existed and it has some pretty good information now that will help alot with getting xp fully compatible

[K4sum1]

Yeah, I only found it because I searched "winvertroll" and wanted to see where I could find it by searching, and landed here. I edited in fixed link. Didn't even know MSFN sent notifications for edits.

I need to get around to trying 1.19 or 1.20 with NotSoNew, that might be a better way to get newer versions on XP since it should work stock.

I also didn't know that and I have to edit my DMs and postings to correct mistakes I usually make until my brain catches it.
