pip install -r requirements.txt
Note that you need the vitasdk toolchain in your path. This tool will use arm-vita-eabi-objdump and arm-vita-eabi-addr2line.
Get a vita core file from ux0:data (a .psp2dmp file). gunzip it, you should get an ELF file.
Run:
python main.py core_file homebrew_file.elf
Note that homebrew_file.elf is an .elf file, not .velf, not eboot.bin. It's recommended that you build it with the -g gcc flag enabled to get better debugging information.
