Half Byte Loader SVN Changelog:
r93
wololo
- added JJS's patch for network modules. This partially fixes issue 109. Thanks
a lot man!
-- see the subject at http://advancedpsp.tk/foro_es/viewtopic.php?f=37&t=784
- removed the code that attempts to delete callbacks. Based on my experiments
with psplink, I'm assuming that unloading the patapon module simply unloads the
callbacks as well. This fixes issue 45
