ShroomTool is a tool to rip out music data (*.SHO) from ZSNES save state (*.ZST) files. It is also capable of making custom sample/instrument set files (*.SHI) to inject into MarioPaint (format). The tool was created as a joint effort between setrodox and Strobe.
This tool is no longer developed as the authors have moved onto other projects.
Mariopants is a tool developed by rainwarrior to compose MarioPaint (format) tunes and exports to SHO format.
