This fantastic ROM hacking utility is effectively a SOR2 character editor. Adding your own custom characters into SOR2 is now a piece of (pan)cake! The possibilities for new ROM hacks are unlimited! (Requires Java).

Exclusive Syndicate Wars hacking features include editing all players, enemies and bosses, and no limit restriction on the number of frames per character. You can re-size animations to add all the extra frames you need. Of course, beware of the 4MB ROM size limit.

To edit SOR2 SW: File - Open with specific guide, then choose the SW guide, then open the SW ROM hack.

Changelog:

1.7 Introduces smart ROM space management when adding new art to the game. It will reuse the art that is replaced whenever possible. Patch 1.7.3 fixes bugs on space management for sprites reused by different animations, as well as an option to turn it off if you’d like art to be generated at the end of the rom as before.

1.6: You can port your characters between SOR2, BKII, Syndicate Wars (SW) and other compatible hacks.
