Kuru Kuru Pyon Pyon: Added hopper emulation. The game is now working
properly without jams. Also added coin counters, coin lockout, and
some extra documentation from Charles MacDonald... [Roberto Fresca]

1010  This hardware seems to be a derivative of MSX2 'on steroids'.
1111  It has many similarites with sothello.c and tonton.c

13  Special thanks to Charles MacDonald, for all the hardware traces: clocks,
14  ports, descriptions and a lot of things... :)

117120  Kuru is the frog sound, and Pyon is the sound of jumps.
118121
119122  Coin 1 (key 5) could be set either as Coin 1 or as Payout button, through
120  a DIP switch. Once pressed, if it's set as payout, the game spits a message
121  that means "Jammed Medal". So set it to 'Normal' for normal behaviour...
123  a DIP switch.
122124
123  If you get the coin jam error, and the game is not responding anymore, press
125  If you get a 'medal jam' error, and the game is not responding anymore, press
124126  RESET (key 0), and the game will reset to default values (even all counters
125127  will be cleared).

194  - Out latch (Hopper emulation?).
195  - Find why the use of payout always jam. Hopper related?
196  - Check interrupts against Charles HW traces.
