you need to edit the client with the novetus client sdk, found within the novetus SDK launcher found here
unfortunately, all included novetus clients have locked clientinfo.nov files for security reasons, however here’s the settings in the client SDK used for 2006S. UI may be slightly different because i use the snapshot. If you’re using an older novetus version, leave it as %args% in the client command arguments field
description:
2006 Simulation
A ROBLOX client from early 2007 modified to look like 2006. Has no animations and the old font. Character customization is limited to body colors only.
If your keyboard has N-Key rollover:
CTRL + SHIFT + D to enable DOF
CTRL + SHIFT + B to enable Bloom
Note that shaders may not work on modern AMD/ATI cards due to shader compilation issues.
warning:
WARNING: This client is known to contain massive security vulnerabilities. If you are planning on playing this client online, use a sandboxing tool like Sandboxie. You don't need to do this when playing solo. This client has been patched to fix these security issues, but more may come up during gameplay. Only play on servers you trust. This is a simulation client. Due to this, the client may be inaccurate in some places.
