PolyMC VS Launcher

No, not really. No one was in charge at the beginning. It was a community project with multiple people having the administrative role at the same time. LennyMcLennington was one of the contributers, but not really an important one. But he removed the administrative rights from the actually important people. Devs like flowln and Scrumplex played a much bigger role. Even after half a year being the only developer at the PolyMC-Project Lenny still heasn't caught up with what other conributers had done in a few months before. See: https://github.com/PolyMC/PolyMC/graphs/contributors

Could I suggest trying a different launcher such as PolyMC? You can get this on deck in Linux linkand sign into your microsoft account to access Java. This version also has the benefit of you being able to get modpacks.

It's still open source, the repo hasn't moved. https://github.com/PolyMC/PolyMC/

The issue is: the main developer freaked out, made a post ranting about political bs, kicked everyone from the GitHub project and now it's been 2 months since it hasn't been updated. The developers who used to contribute to "PolyMC" moved from the "PolyMC" project to the "PrismLauncher" one after the drama.

There was no prompting or provocation towards lenny at all. The code of conduct existed for ages before lenny deleted it on oct 17 2022: https://github.com/PolyMC/PolyMC/commits/358f080c76dbdfc65f32e08448a5e38b78d2bab0/CODE_OF_CONDUCT.md

PolyMC: https://polymc.org/

for polymc literally yes git commit (got deleted but title is there)

First, it's gio that handles trash in SteamOS. Second, after digging into PolyMC's code, it also leverages trash. Was added roughly 7 months ago in this commit: https://github.com/PolyMC/PolyMC/commit/02f30de1c11fa53e61c199032a3280afe618e3b2

Here is a link to Modloader for MCb173. It needs adding directly into the minecraft.jar file, however if you use a launcher like MultiMC, which you can find here: https://multimc.org/ then there is an option to 'add to minecraft jar file' which does the same thing.

I used to have this issue lots, and it was due to my internet being too restrictive. The Minecraft Launcher was refusing to open, and I fixed it by messing with the restrictions until it worked. Hopefully this helps :) if all else fails of course, try just reinstalling it! I’m sure that all your config files don’t get affected by reinstalling it, but just in case make a backup. And if all ELSE ELSE fails, you could switch to a completely different launcher, like MultiMC! Good luck!

If you are willing to try out the launcher - MultiMC which you can find here (there is a Mac option available) : https://multimc.org/ then I have put together an MCb173 pack that has been made for MultiMC. You just use the 'import from zip' option.

Download MultiMC from their official site https://multimc.org/

Others than that, if you insist, you can take a look at the launcher which u/reginakinhi provided or find others on the internet (GitHub for example). Since PrismLauncher is written in C++, and if you are not familiar with it, you should see other launcher as well. Or else https://github.com/MultiMC/Launcher is an alternate.

The best way to experience beta 173 is to play beta 173, and perhaps add some mods to it a little later. One of the better launchers to use for old versions and for playing modded is to use the MultiMC launcher which you can find here: https://multimc.org/

This will only assist if you are using MultiMC as your Minecraft launcher as it is a MultiMC instance which you can use the 'import from zip' option. MultiMC can be found here: https://multimc.org/ It includes IC2 1337 with several add-on mods which have also been back-ported to work with it, such as the Thermometer, Advanced machines, etc. You can disable the add-ons you do not wish included. There is also buildcraft and redpower added as well.
