Update: The MC2USB-Tools called 'PS3MCA-TOOL v1.3' which were released yesterday by our valued PSX-Scene-Developer&Moderator Jimmikaelkael and an anonymous hacker/source, along with the 'FMCB 1.8c-Loader' actually grants FULL ACCESS TO PS2 MEMORYCARDS!
Here's a list of commands:
Copyright (C) 2011 - jimmikaelkael & 'someone who wants to stay anonymous'
./src/ps3mca-tool <command> [<arguments>]
--mc-image, -img <output filepath>
--list, -ls <mc path>
--extract-file, -x <mc filepath> <output filepath>
--inject-file, -in <input filepath> <mc filepath>
--make-directory, -mkdir <mc path>
--remove-directory, -rmdir <mc path>
--remove, -rm <mc filepath>
--file-crosslink, -cl <real mc filepath> <dummy mc filepath>
--content-key, -ck <disk kelf filepath>
--sign-kelf, -k <disk kelf filepath> <card kelf filepath>
So beside being able to create multi-region-installs and those other features you can see at the other news-post, there are also these features (as of yet) already integrated:
-Get free MC-Space
-Dump&Write binary MC-Image (Virtual MC-Images used in 'OPL'!!!)
-Basic file- and directory-creation&access (read/write files and folders from/to it + delete/undelete files and folders)
About the FMCB-Loader it comes with:
-Compared to the FMCB 1.8/1.8b-Loader (the same in both versions), this one comes with the feature of fixing the Protokernels (a 'memory clear issues' with the ExecPS2-Call) on old consoles during runtime [when it/FMCB is started].
This fixes a few programms, which are normally incompatible to those Versions, like ESR and Cogswap.
-The generated KELF is 100% SONY-Free! That means, we can provide pre-encrypted 'Disc-KELFs' legally and everyone can re-sign them for their MCs to 'MC-KELFs' by these tools.
That's thousand times better especially for those who install it for others, since the KELF previously were re-signed DVDPlayer-KELFs from the PS2s ROM.
-Multiregion-Install is now possible from any PS2 for all regions!
There is no PS2-side Homebrew-Programm a.k.a. new 'FMCB-Installer' currently supporting those new features, but Jimmikaelkael announced that he might work on it in his free time...
