Description
Based on the research in the op-forums custom firmware thread. Unpack and repack subcommands expose the files inside an official .op1 update, an analyze subcommand reports build version and bootloader version, and a modify subcommand applies predefined mods: iter, presets-iter, filter, subtle-fx and graphics changes (iter lab visuals, inverted tape screen, CWO animal swaps). The README says mods were tested on firmware 235 and warns that a bad build can brick the unit. It can only change what is already in the firmware; new features cannot be added this way.
Install notes
Install with pip, unpack your own official firmware file, apply mods, repack, then update the OP-1 through the normal update mode.
