The Sonic Retro Community SVN Project (an idea originally proposed by Tweaker) allows members to collaborate on projects such as disassemblies and programs. As the name suggests, it uses the subversion revision control system to enable multiple members to easily work together on projects of common interest. The repository commit path is http://sonicretro.org/asm_svn, and a web version of it can be accessed at http://svn.sonicretro.org.

Hosted Projects

The repository currently hosts the following projects. Before uploading a new project, post about it in the
Sonic Retro
forum
so it can be decided whether the project merits inclusion.

Knuckles in Sonic 2 disassembly

Puto has uploaded his disassembly of Knuckles in Sonic 2 onto the server. It is incomplete in the sense that shifting code and data around produces a non-working ROM, and its main use thus far has been porting the Knuckles object contained in it to Sonic 1 and Sonic 2.

Sonic 3D Blast disassembly

The Sonic 3D Blast disassembly in the repository was uploaded by Sik. It is not a complete disassembly, although some major routines, including ones which handle level loading, have been identified and labelled.

Sonic Adventure DX (PC) disassembly

MainMemory has uploaded his disassembly of Sonic Adventure DX: Director's Cut (PC version) in the repository in June 2010.

Sonic & Knuckles Collection disassembly

MainMemory has uploaded his disassembly of Sonic & Knuckles Collection in the repository in June 2010.

Sonic the Hedgehog disassembly

The Sonic the Hedgehog disassembly on the SVN is an updated version of Hivebrain's 2005 disassembly. It is now based on ASM68K, adds symbols for the RAM variables and other constants, as well as macros. Some labels have been replaced with local labels. Also, the code has been split to separate files (only data was split in the previous version) and the ability to switch revisions from the original version to the Japanese Rev01 version has been added using a variable.

Sonic the Hedgehog 2 SMS disassembly

Glitch uploaded his disassembly of the Master System version of Sonic the Hedgehog 2 in February 2009. It can be changed to build the 2.2 version of the game using a variable. One major thing to note that this disassembly uses Z80 ASM instead of the 68K language used in the Sega Mega Drive disassemblies.

Sonic the Hedgehog 2 disassembly

The Sonic the Hedgehog 2 disassembly on the SVN is based off Xenowhirl's 2007 disassembly. It was uploaded by Scarred Sun, then FraGag quickly committed some important changes. The disassembly has since been worked on by numerous other contributors. Major additions include a dynamic IDs system which allows entries to be removed from tables such as the game modes array without having to change hardcoded constants throughout the game, a more dynamic way to declare the RAM variables, and the labelling and commenting of numerous routines.

SonicState

SonicState is a savestate editor written in C# by Delta. It is currently incomplete, although Delta plans to update it.
