+[Fork of Pazaz/RT4-Client](https://github.com/pazaz/rt4-client)
+
+## Goals
+
+* Identify all classes
+  * Create new static classes by grouping related members
+* Identify all methods
+* Identify all fields
+* Identify all local variables
+* Remove any remaining obfuscation (possibly none left)
+* Fix poor decompiler behavior (fernflower)
+* Replace magic numbers and bitmasks with named final fields
+* Refactor code to improve behavior/readability
+* Modernize code/libraries (High DPI support, modern refresh rates, ...)
+* Support existing servers via global config flags that adjust packet behaviors
+* Organize classes into packages
+
+OpenRS2 annotations are left in the source to build a deob map from, in case some of my changes aren't desirable.  
+That mapping can be used to generate a new deob with everything renamed for you.
+
+## Instructions
+
+Build requirements:
+* Java 8+
+
+Runtime requirements:
+* SD: Java 8+
+* HD on Windows, use Java 15 or lower. There is a JOGL issue on 16+ related to how they grab the WGL context from the window.
+* HD on Linux: Java 8+
+* HD on macOS: Not possible yet on latest macOS. Might work for earlier OS versions.
+
+```
+git clone https://github.com/Pazaz/RT4-Client.git
+cd RT4-Client
+./gradlew run
+```
+
+You will be connected to a test server automatically.  
+This server is provided by 2009scape for their own internal developments.
+
+## Deviations
+
+Configurable:
+- Packet behaviors to make it compatible with existing servers
+- View distance in HD
+- Bilinear map filtering in HD/SD
+- Tweening enabled by default (existed in client)
+- Shift-click behavior on inventory items enabled by default (existed in client)
+
+Unconfigurable:
+- JOGL was updated to 2.4.0
+- Update/render loop was decoupled to tick indepedently from each other
+- Camera panning input rewritten to use render loop timing
+- Varp array size was extended to 3500 instead of 2500
+- Mouse wheel camera movement (click middle button and move mouse)
+- Render FPS is set to your monitor's refresh rate
+
+## Libraries Used
+
+- JOGL/Gluegen 2.4.0rc
+- Google Gson 2.9.0
