RNG lua script i’ve found works on VBA but not Bizhawk, presumably it was written for the former and not the latter and there’s some difference in format there (though i’ve no idea how either system works or would differ)
The function that finds total assets should be at 0x80B6550 (FE7U)
, it would be called every time the game wants to get the funds rank; it doesn’t store the result anywhere long-term.
