Summary	04534: 3bagflvt, eforesta: Coin Diverter Fault after accepting 5 coins
Description	I may as well add this, although it's been known for quite a while. Upon entering the fifth coin, the game will freeze with Call Attendant - Coin Diverter Fault. No other games in the driver are affected. Fault can be cleared by opening/closing the main door (M) or resetting the machine (F3). The only two games which have this error are both Australian versions, every other game in the driver is either New Zealand or US region, and neither exhibit this bug.
Steps To Reproduce
Additional Information	The regression was during the aristmk4 updates added after the 0.140 release; the buggy RTC was also disabled during this update (the RTC isn't even populated on most PCBs, and was causing all games to hang in the test mode). The original 0.140 release doesn't have this bug.
