A Super Mario 64 Level Editor. Currently in Public Beta form.
Super Mario 64 ROM Extender 1.3b
This tool will create a decompressed version of the Super Mario 64 ROM using the ROM you provide. It takes the MIO0 compressed data and appends the decompressed data at the end of the ROM file, with some extra space for future expansion. Important note to Mac users!! The previous 1.3b version had a serious bug which prevented it from running on OS X, you should download the new 1.3.1b version. New: Version 1.3b will now pad the ROM with 0x01 in the Mac version, to match the Windows version. A bug in the Windows version where the MIO0files folder would not be created when unzipping should be fixed. New: Version 1.2b improves error handling and ROM version checking. You will need this tool to be able to use Toad's Tool 64! Note: This page will not provide any ROM whatsoever.
