/*
* File: z_pause.c
* Description: Frame Advance debug feature
*
* This allows you to advance through the game one frame at a time on command.
* To advance a frame, hold Z and press R on the specified controller (see z_play).
* Holding Z and R will advance a frame every half second.
*
* Note: While the system is fully hooked up, there is no way to enable it in game
* Instead one would have to add something like:
*
* if (CHECK_BTN_ALL(input->cur.button, BTN_R) && CHECK_BTN_ALL(input->press.button, BTN_DDOWN)) {
* frameAdvCtx->enabled = !frameAdvCtx->enabled;
* }
*
* to the start of FrameAdvance_Update, which would allow the system to be toggled on and off by holding R
* and pressing Dpad Down on the specified controller.
*
* Note2: Controllers 2-4's inputs are normally zeroed out, so this would also need to be fixed to use frame advance
