This repository includes a 2021 build of Roblox's RCCService (which stands for Roblox Cloud Compute Service). RCCService is responsible for rendering Roblox's avatar thumbnails and hosting servers.
Be careful and know what you're doing, because 2018< RCCService builds are known to log your IP address to Roblox and can potentially result in an IP ban from the website.
The bootstrapper is difficult to run now, so use something like 7-ZIP to uncompress "RCC.sha256".
