hello there are an unlimited amount of platinum idols because they auto generate. I believe its .5% for regional and 1% for nationwide. The only cheat that could be of use is using the C key to instantly do nationwide auditions (use the Y key to spawn more money as the auditions still cost 10m) the way to turn on cheats is by pressing F7 multiple times. But don't quickly spam the C key or it'll crash the game
