root/rarfile.patch

Revision 1, 1.3 kB (checked in by jmoiron, 2 years ago)

Initial commit. Some things are working quite nice
at this stage, in particular:

  • datfile.py basically supports romcenter and clrmamepro
  • ndsencrypt supports arm9 encryption for secure area crcs
  • ndsheader supports *most* of the output of ndstool -i

In addition, rarfile.patch is included here. It contains
the changes made on the rarfile.py library (which is a
standalone file and is encluded in romutil, but unfortunately
is linux only.. looking into a replacement but not sure
if one is possible or exists)
