Integrating MC 1.2.5/Forge with native launcher

[AnrDaemon]

Hi there.

 

I'm trying to pull my old game up into native launcher for easier access. But I'm having little success.

 

The game starts fine, if I use old launcher or start the Jar anonimously.

 

What I've done so far:

 

1. I've installed vanilla 1.2.5 in native launcher.

2. I've created a new directory in <versions>, named 1.2.5-Forge-3.2.3.108-plus

3. I've copied vanilla 1.2.5.json into a newly created directory and named it "1.2.5-Forge-3.2.3.108-plus.json", also placed a modded client JAR with equivalent name there.

4. I've changed 

"id": "1.2.5-Forge-3.2.3.108-plus",

in the JSON file.

 

Launcher sees the forged version and attempts to start it, but then it hangs infinitely on logo screen.

 

Anyone have any good ideas on how to proceed? Or should I forget it and don't even bother trying?

use multimc http://multimc.org/

Great suggestion. Indeed.

But it doesn't answer my question.

So, I've got a little further, but not by much.

MC now proptly crashes with

ModLoader 1.2.5

The answer to your question is: Don't. You are using the wrong tool for the job.

Are you telling me that multiversion launcher is not the tool to launch multiple different versions?… I got it right?

(Besides, I don't like MultiMC a single little bit.)

In other words, I need a custom launch wrapper? Thanks.

No, you need MultiMC

You know, this is not helping? If you just tried to make a joke, it fell flat on its face.

[loordgek]

no he is not

you can do it which the native launcher but is a pain in the ass (pita)

so if you want to safe some time, use MultiMC

It is well over 20 years that I do not follow "use that" advices blindly.

I did see that "MultiMC" and I do not like it a single bit. Though, I said that already.

Case closed. Thanks for participation.
