I will provide an NTR plugin and an executable which can patch a romfs.bin.
Methods:
1. You can extract romfs.bin from a cia, patch it and rebuild a patched cia.
2. You can just use the NTR plugin with NTR CFW.
3. IF HANS should work you can use a patched romfs in the HANS folder (shortcut etc. willl be provided).
Note:
IF braindump works (which i doubt) you can dump a romfs.bin from the cartridge, if not you will have to acquire a romfs.bin elsewhere.
prepatched cia's are expected to pop up (built by using method 1).
This is what you can work with. The rest is up to you.
