This is a easy Drag and Drop bat file that converts NSPs to XCI.
Just drag one NSP onto NSP_2_XCI.bat and all NSPs in the folder you dragged it from will convert to XCI.
Requirements:
Python needs to be installed. I tested python 3 but 2 should work.
keys.txt needs to be in "tools" folder.
Does it cleans the ticket and cert before converting to XCI?
