Automatic ROM Patcher

Apply the stage-transition fix in your browser without uploading your ROM.

Choose the source ROM to automatically apply the stage-completion crash fix. Processing stays in your browser, and the result is saved as a separate file.

No matching SHA-256 is required. The patcher accepts 512 KiB ROMs whose target instructions and free space match the expected bytes. These local checks do not establish that the called routines or other code are compatible. Chinese and other builds have not been tested.

See Creating the IPS Patch for the correction details and the Node.js tool, which retains strict source-ROM verification.
