This page is intended to disambiguate between the various versions of practice hacks which exist. Some versions of Infohud may require you to apply an IPS patch to your copy of SM. Lunar IPS is commonly recommended.
All versions of the practice hack should offer an option with the "SD2SNES" savestate feature enabled, and another option without. If you are not playing with the SD2SNES cartridge (or Super NT with latest firmware) then you should choose the option without savestates. This feature will likely cause crashes if used with emulators, everdrives, or virtual consoles (SNES Classic included).
Infohud version 2.0 <-- RECOMMENDED
Total built a new webpage for SM Practice version 2.0, which was developed by Pinkus. This should be the most up-to-date version of the Infohud practice hack used by speed runners. It offers a how-to-use tutorial on its Help page and should be read by first-time Infohud users.
This is the source repository for the Infohud practice hack, allowing you to see how it works, adapt it for SM romhacks, contribute to the project, or build your own customized copy from the files available.
This is the most up-to-date version of Infohud available for PAL region roms. PAL is no longer supported in the main branch as of the version 2.0 rewrite.
This is a branch of the 1.42 version of Total's Infohud. It adds an additional Rerandomize feature which changes the rng seed every time a savestate is loaded, and also permits users to set specific patterns for Botwoon and Phantoon. These features are also present in the version 2.0 rewrite.
This was Total's last offical release of the Infohud practice hack before version 2.0 by Pinkus. Practice roms for Kaizo Possible and SZM, as well as a guide to adding the SD2SNES savestate feature to other romhacks, are also available here. The "Minimap" version is only available here.
