(NOTE: On a real NES unit, if sprites are disabled (D4 of $2001 is 0)

refresh cycle).

What is meant by this? Does it mean that it degrades so that if display is turned back on without upgrading the SPR-RAM (i.e. sending the sprite data to it again), then the display will be messed up--or does it mean that the SPR-RAM will permanently degrade (i.e. you'd have to get a new system)?
