Novetus

What works

TL:DR The launcher works, so do the preinstalled clients (some of them have minor glitches). I was able to change my username/ID and customize my character. Play Solo works, so does hosting or joining a server. Most of the options/settings worked, so did the SDK, for the most part. It is pretty much perfectly playable on all clients. Sideloading other clients (such as unofficial 2012M & 2013E) is also possible.

What does not

• SDK — Roblox Legacy Place Converter (does not launch)
• Launcher Style — Stylish (must be manually selected by editing config file, causes the launcher to crash on startup)
• Launcher — Options: Local Play (can't enable)

Workarounds

• Launcher does not work — Create wineprefix using winetricks (should automatically install required dependencies) or install dependencies manually using dependency installer in bootstrapper. The minimum that you will need to install is .NET, with other dependencies being required for certain features.
• Delayed start on launcher (launcher takes about 1-2 min to open) — Use 32-bit wineprefix
• Graphical glitches in some clients — Change renderer to GL Stable/Experimental (Options > Settings > Graphics Mode)

• Launcher — Discord Rich Presence

• Launcher — ReShade

Additional Comments

To run it, extract the downloaded archive then launch NovetusBootstrapper.exe. Custom preferences, clients, assets, etc. are saved in the same folder. Make sure to run it in a 32-bit wineprefix!

You will need to create entries in your app launcher manually.

To play with others on a server, you can port forward, or use a service like playit.gg.
