PREPARE is a tool to write and sign the DSi's HWInfo, a per-console file containing the serial and region. HWInfo is required to boot final firmware (ignored on factory firmware) and so PREPARE is used to prepare the DSi for IMPORT.
There are two versions, PREPARE and PREPARE SD. The only difference is that PREPARE SD does not include "WRITE SDMC-LNC" (the SDMC Launcher), while the normal PREPARE does. There is also a PREWRITE which is very similar in function to PREPARE with a few additions, though PREWRITE is likely not used.
The tests for both PREPAREs are listed below:
