tstrbx

This launcher has no regards for keeping your servers safe aside from FilteringEnabled. All the files are called "tstrblx" because I made a spelling mistake when making the launcher gui and decided tstrbx sounded nicer.

I haven't tested 2017 and 2019, if you can even get 2019 running. 2018 FIBv12 works fine in my testing, though doesn't remove all the studio bits when joining a server for some reason.

You have to provide your own clients, I'm not giving them to you. They also have to be studio clients.

tip: you can still download 2020E+ clients from ROBLOX servers. I'll let you figure out how to put everything together.

another tip: https://archive.org/download/roblox-clients-2006-2021 and https://archive.roblonium.com/Client/Windows/RobloxStudio/

v12 Future-is-Bright is (apparently) a 2018M client. It feels more like a 2017 client though. Early Future-is-Bright builds are 2017. The only avatar-evolution build is a 2020E client.

May 2020 and above clients have broken corescripts, as they (probably) get big parts of the CoreGui from ROBLOX servers or something like that. I honestly don't know.

Compiling

You really want to compile this? Well then, beware, the code is bad. A never-nesters nightmare.

  1. Clone the repo
    • Surely you know how to do this. For the three people that don't know this
      git clone https://github.com/MonkeTGG/tstrbx.git
      cd tstrbx
      
  2. Build
    • Open it in Visual Studio (I used 2022. should be compatible with 2017+, but does use 2022 build tools).
    • Ctrl + Shift + B.
    • Wait

It should now be in tstrbx/tstrblx/bin/Release/tstrblx.exe, or tstrbx/tstrblx/bin/Debug/tstrblx.exe depending on how you compiled it (it doesn't matter, they're both the same).
