its something like 3.6 Million on Graal PC. Not sure if iClassic also uses the player.rupees as a script command or if they stored them in a clientr.flag. If they stored it in a clientr.flag you can have unlimited gralats I gues else like I said something like 3.6M. I even gues it would be PI (from math) * 1Million

Fail fake. Blured numbers and so on.
