Saxman's Sonic Boom Engine is now on GitHub: https://github.com/saxman727/sboom Please create a new branch if you plan to make modifications! I think 'tedious' would apply if someone wants to use a hex editor to change the levels. On the first post of this topic, I included a link to some level format conversion tools I wrote to port Sonic 2 levels to Sonic Boom. If MainMemory adds Sonic Boom support back into his editor, then that will allow larger zones to be created. Then, the only thing to really do at that point is update my tools to be able to merge physical and visual files since there's no level editor yet that supports this concept. You should use it for the hacking contest next year! I would like to see how many people will pick it up.
