Just trying things at random, dlls in extra/cyclone and other folders seem to load with no problem. Zexy is weird because many of the objects exist as both dlls and abstractions with the same name, like a2l.dll and a2l.pd. The abstractions load OK but not the dlls, even [0x3c0x7e] loads OK, while 0x2e doesn't because it only exists as a dll.
