This is something ffgriever should reply to, but my guess is that some part of the FMCB booter or the loader it launches does the equivalent work needed for DVDV access. IMHO it would only be natural to build that cdvdinit into the basic FMCB booter.
And one last question... FFGRIEVER said this "IMPORTANT NOTE: The ESR application requires my cdvdinit fix to be loaded first, so either use FMCB with default launcher (it will contain my fix) or launch it manually (using RUNME1.1a)."
Why is it working for me if i don't have installed the default FMCB launcher?
I mean... i installed the FMCB 1.4 but i used the light launcher (75kb) and he says that you have to use the default loader (i understand it is the big one that installs if you dont have an own dvdelf, i dont know because that option never worked for me). But it works for me with the light dvdelf. Is it supposed to?
