With ps2 save builder you can make a .max file with the exploit.
Open your system configuration save file in the program and insert the boot.elf in the save file. Also add the titles.db which tells the ps2 which ps1 games can be used for booting. Uncrunch it on the mc and you're done.
All the other files can be launched from pendrive (mass device), but you can also add them to the system configuration file (if there's enough space avail)
