RSC Sundae is an open source remake of the original RuneScape Server and Runescript API, using only data sources and packet captures from the original server.
It’s the most accurate replica of RSC ever made, and the only one that accurately models NPC behaviour, among many other behaviours.
A webclient (native compiled webassembly), android client, and desktop clients are available. These are native for each platform and utilize the ultra-lightweight RSC-C remake rather than relying on Java.
RSC Perfect is the live hosted version of Sundae which implements all RuneScape Classic content up to the final F2P-only version (10th December 2001) with mechanical and bug fixes from later versions. It contains no modifications to the original content. However, the following extra features are available in Perfect:
- Selectable 1x or 4x XP rate
- Official self-sufficient (“ironman”) and no-banking (“ultimate ironman”) modes
- Extra hiscores for e.g. PKing, lowest level Dragon Slayers
