Podoboo is an open source dynamic launcher and wrapper that is configured to help with your usage of Super Mario World hacking tools. Before using any programs that could hurt parts of your ROM or cause unintended consequences, Podoboo makes an automatic backup. Podoboo also manages launching other common hacking tools for SMW so that you can open them easily all in one place. For tools like Spritetool and Gopher Popcorn Stew, it also manages your list.txt in a more user-friendly manner.
