// YHGJ - Houkago Shounen (Japan)
//
// This game has a save speed race condition leading to a softlock. The game will draw a face in the notebook during the
// card async wait, and once the face is finished, set a flag to advance the menu state. But if saving finishes too quickly,
// it will exit the async wait, stop calling the face-drawing function, never finish it, never set the flag, and become stuck.
// To fix this, part of the saving function is rewritten to include a check for if the async wait idle callback function is the one
// that draws the face, and if this is the final block of save data to be written (saving happens in four blocks).
// If both of these are true, then it will loop calling the save idle callback until the menu advance flag is set.
