Well, these names were all intentionally obfuscated on the homebrew SDK as the original developers were quite "anal" about NOT USING OR REFERENCING sce conventions. So all of that is just meant to avoid people doing things like HDLOADER/OPL/COGSWAP/SWAPMAGIC, etc ...
How ironic, the same guy who wrote HDLOADER wrote these high level FS libs ATAD (ps2hdd.irx, apa.irx) connects on to give APA and PFS access to apps like uLE ...
When PS2 dev forum was "till alive" and you asked there about SCE specific stuff you would be made ridicule of and then banned. So much for that policy now, the original authors are not around anymore besides a few guys who "wouldn't give a f**k" about what happens with the SDK at this point... Very few people are dedicated to this "scene" now.
And SP193 you're one of the few late heroes we had. Hope you are still somewhat accessible when army "swallow you up". I really enjoy talking to you. m(_ _)m
