That mechanism is exactly what FreeMcBoot uses to start the elf on the memory card.

So, what we are exploiting here is exactly what you were wondering about.
Imagine if this hack was on the DVD driver... It would require a DVD video disc to start our ELFs... Not really any better than the PS1 exploit, right ?
Ah ... Now you can say that the PS2 has cartridges !!!! LMAO
