Improvements to Lucky74.c driver:

Browse Source 
- Reverse engineering of custom IC's 06B49P, 06B53P & 09R81P.
 - Mapped the missing 3x SN76489.
 - Measured and traced all clocks on the board.
 - Measured and fixed the interrupt system.
 - Implemented timings/clocks from custom 06B49P.
 - Added sound support. All regular game sounds/musics are working.
 - Implemented the ADPCM samples system through 09R81P + M5205 emulation.
 - Added pinouts and technical notes about custom IC's 06B49P, 06B53P & 09R81P.
 - Added flip screen mode.
 - Inverted the order of double-up difficult DIP switches.
   (Seems to be the opposite of the indicated in the instruction sheet).
 - Changed 'Key In' to be active LOW instead of HIGH (checked in the PCB).
 - Complete memory map and ports scheme.
 - Created handlers for USART port and co-processor communication.
 - Renamed the sets accordingly.
 - Updated all notes.
 - Cleaned-up the driver.

Regarding the abobe diagram, there are 2 different states controlled by some bit.
Each state drives a different palette that will be assigned to each graphics bank.
Regarding the abobe diagram, there are 2 different states controlled by both 06B53P.
Each state arrange a different palette that will be assigned to each graphics bank.
As we can see here, same pin of different PROMs are connected together in parallel.
We need to check the pin 13 (/G1) and pin 14 (/G2) from each PROM to see if they are
connected to the same signal, and futhermore check if one or the other is tied to GND.
To reproduce the states, we need to create a double-sized palette and fill the first
half with the values created through state 1, then fill the second half with proper
