On another forum, someone (Fogbank) reported that the clicks associated with DVD-R boot when using the R-Mod disappeared when using the Messiah.

After a bit of toing and froing on the subject, we deduced what was happening - explaining a large number of similar past questions.

With the R-Mod, the laser focuses first on the GS2 CD; it then has to read a DMC DVD onto which it re-focuses. Butr when the swap occurs, the lens no lonher re-focuses as it's made the sweep on the DMC original. But so far as I know, if it then fails to focus on a DVD-R at any point, it clicks an retries.

Now with the Messiah, there is no swap so the initial focus set by the groove sweep on the DVD-R is good. So although the Messiah does in no way govern the laser, the fact of direct booting causes a different focus strategy to occur from previous modchip mechanisms.
