I am unable to patch a game with the Open world state. I'm more or less following the readme sample docs. Patches do seem to be applying. Uncle's text is changed, the chest in link's house is randomized and the opening menu is patched to alttpr custom and to show the validation code items, but initial game state is raining instead of open.
I have tested patched roms in bsnes on windows and snes9x on ARM (raspberry-pi4), same behavior on both.
